I have addressed these issues with security certificates (see attachments). In firefox I just started getting everything but not seeing anything, especially related to my problem. Should I be in If not, if I'm in the right forum.

However, he enters the page by entering the data. Or if the site I'm logging into is trusted, saying "This connection is not secure, the credentials I entered may be vulnerable." will my modem data be stolen? My question is can Microsoft Edge do not get to the page when using Mozilla Firefox.

In any case, highly sensitive data is protected.
This is very unlikely, if you have a wired network they can cover them *** in court if there are any problems...am I doing this? But there is a reason warnings exist.

I mean... it should be unlikely. The most common way, but also very unlikely.... But I don't want to, however, still... Basically IE just reminds you that when you check it... the messages stop.

They tell you this for more legitimate reasons so that your incoming/outgoing data is not encrypted..... I know there is a box, but it's a little more likely if you have a wireless network. Like my question... how do you stop with Matthew.

Connecting wirelessly to a local device by IP address "connection failed"

When I right click I get one of the options (if any) I need to troubleshoot. Now, however, for no reason, whenever I enter the MAC address, the unique ID and the IP address. All I had to do was enter the IP address to figure out why suddenly the network/DVR wouldn't connect. PC and DVR are in

For some strange reason I have DSL and I've never had it before and the updater doesn't work at my school.

The first hint is the usual AVG icon in the problem until recently (now almost every day or two). If I manually open Control Center, I see a "Connection Error" note. There is an exclamation point in the Quick Launch area. Conflict between "Wireless Network Connection" and "Local Area Connection"

I set the router's IP address to max! The wired connection shows 192.168.3.1. Everything connects perfectly! For the displayed router address, all devices that connect to the AREA NETWORK and WIRELESS CONNECTION AT THE SAME TIME! You should know alternative configurations

Disappointment 192.168.3.1 Everything is great! Do you want your router to offer DHCP in the range 2->32 (it's more, but doesn't work ("connection timed out" or "page not found" errors). When I connect to wireless network, it all connects, it *should* be 192.168.3.x where x > 1 and<255.

Running XP some static configuration data in devices.

Can they get involved to tell me how to fix this? When I connect to the wireless network everything connects, the IP address is 192.168.2.1. The wired connection shows Area Area, the Internet connects perfectly. I suspect you have the wrong xx2.1.

I set the router's IP address to the router. Remove anything but it doesn't work ("connection timed out" or "page not found" errors. If I disable my local IP address 192.168.2.1. Click to expand... Thanks!!!

When visiting websites, we usually look for useful or interesting content. But sometimes, when opening some resources that previously worked correctly, we see a message that it is currently not possible to securely connect to this page. We will consider the solution to the problem that has arisen, as well as the reasons for its occurrence in a number of situations, in today’s article.

It is not possible to connect securely to this page because the site is blocked by Roskomnadzor

The active activities of Roskomnadzor have recently affected not only Telegram, but also other “innocent” resources. Thus, users report that when they visit the same site throughout the day, it opens and then the message “” appears. The problem may be detected when accessing only one resource, while the rest are working normally. The reason for this behavior was also found - some of the IP addresses provided to a certain site were blocked by Roskomnadzor. As a result, if the user lands on such a blocked IP, the page does not open. If the IP address is not among the suspicious ones, then the resource calmly provides access to its data.

What can you do to still get to the right site? Technical support engineers for Internet resources advise using all possible methods that are not prohibited by law to bypass the blocking.

Roskomnadzor “does not sleep”

Inability to display https

One of the reasons that you cannot connect securely to this page may be impossibility of data processing transmitted over the https protocol. The user encounters such problems when he tries to log into his personal account on government portals (for example, zakupki.gov.ru or bus.gov.ru). The page does not open and a message appears stating that it is necessary enable TLS and/or SSL cryptographic protocols. What to do in such a situation? If everything worked fine before, then perhaps the reason is due to automatic installation updates for Windows 10. This OS has recently become widespread among users and Microsoft releases most updates specifically for this operating system.

Right-click on the “Start” button and select “Run”. First we enter the command regsvr32 /u cpcng –> OK, then regsvr32 cpcng –> OK. If the problem continues to exist, we try other ways to solve it.

The use of TLS and/or SSL protocols is not enabled

In Internet Explorer 11, the TLS and/or SSL protocols are enabled in the advanced browser properties in the “Security” block. To get there, you need to click “Tools” -> “ in IE Browser properties”.

Making changes to browser settings

We tick the required boxes and click “Apply” -> “OK”.

You can also add the site to the list of trusted. To do this, go to the properties of IE11 (“Service” -> “ Browser properties” -> “Security” -> “Reliable sites” -> “Sites”) and enter, for example, bus.gov.ru into the zone of trusted websites, before unchecking the box “For all sites in this zone, server verification is required (https)".

Configuring security settings in browser properties

Solving the problem with the proxy server

If you are using a proxy server for your network connection, to prevent the message “Cannot connect securely to this page” from being displayed, configure its operation correctly. Open the Microsoft Edge browser, click on the 3 dots in the upper right corner and open “Options” -> “ View additional options” –> “Open proxy settings" A window like this will open.

Open the proxy server settings

You can completely disable the proxy by moving the cursor to the “Off” position, or place the necessary addresses in exceptions section.

No access to TCP port 443

Lack of access to TCP port 443 can also cause the “Cannot connect securely to this page” error.

In this case, you need to do the following.

  1. Right-click on “Start” and select “Run”.
  2. Enter cmd and confirm OK.
  3. In the window, type telnet bus.gov.ru 443 –> Enter.

If it was not possible to connect to the host through this port, information about the failure will be displayed. If the system operates correctly, all previously entered data is cleared and here it is necessary to contact the system administrator to obtain information about the correct data for configuring TCP port 443.

Problem with root certificates

It happens that after some failure or update it is necessary reinstall root certificates. To do this, download the certificate from the website of the certification authority that previously issued it.

Then we do the following:

  1. Open the certificate that you saved on your computer and install it.
  2. In point " Place the certificate in the following store” through “Browse” select “ Trusted Root Certification Authorities”.
  3. Confirm OK and complete the installation by clicking “Finish”.

Problems with CryptoPro CSP

There can be several sources of failure. Let's look at the most common ones.

Problem: Solution:
CSP blocks CryptoPro program antivirus, other crypto provider or malicious code

Due to the increasing frequency of blocking of web resources, an increasing number of users have to deal with access errors. However, they may not always be related to sites being blocked by providers; the problem may be hidden on the computer itself. This is an error, and it does not matter which browser is used.

The error may occur due to the lack of a certificate on the site confirming the safe operation of the browser with this site. SSL , also the reason for its appearance may be related to changes in the settings of the software responsible for system security. Today we will look at one of the most common variants of the above error, in which the user receives a notification "Website "URL" sent an invalid response. ERR_SSL_PROTOCOL_ERROR" .

We can say with a greater degree of certainty that everything is fine with the site itself, however, you can check its availability using some service like ping-admin.ru won't hurt either. If the resource is available, you should look for the causes of the error on your computer. There may be several reasons. If the site uses a connection HTTPS first you can check if the protocols are enabled SSL2 And SSL3 in browser properties. Open the classic control panel, launch the applet.

Switch to tab "Additionally" and make sure that in the checkboxes SSL 2.0 And SSL 3.0 checkboxes are checked.

At the same time, check if it matches time on a PC with your time zone. If not, set the correct time and enable synchronization.

Alternatively, you can try disabling protocol filtering HTTPS , although it is undesirable to do this, since this reduces the level of security. In , for example, this can be done as follows. Go to internal address chrome://net-internals/#hsts , select from the menu on the left HSTS, in field "Delete Domain" insert the address of the problematic site without the prefix HTTPS and press "Delete".

After this, you will be able to log into the site using the usual protocol. HTTP .

Note: Before making changes to protocol processing settings, you need to completely clear your browser cache and delete saved files cookies, and then try to access the site. If the login is completed without errors, with filtering disabled HTTPS there is no need to rush.

There is a very high probability that access to the site is blocked by the anti-virus software installed on your computer. Sometimes the cause of the error becomes obvious after enabling private mode in the browser (incognita). Here, for example, is what it shows when going to a blocked site in incognito mode. In this case the error "This site cannot provide a secure connection" causes antivirus .

Therefore, you need to either disable real-time protection in this program, or add the blocked site to the exclusion list.

The settings of other antivirus software are checked in a similar way. In particular, users had to deal with the described error Dr.Web (firewall settings) And ESET NOD32 ("SSL/TLS protocol filtering" setting) . At the same time, you need to check the operation of the extensions installed in the browser, since some of them, in particular, SaveFrom.net may interfere with normal operation of network resources. And one last thing. If you receive an access error when opening a site, use the most common anonymizer, or even better VPN -service, in most cases these tools allow you to bypass such restrictions.

The growing trend toward privacy protection among browser developers is good news for all users, but sometimes security can be too much. This situation can be seen in the example of blocking sites: “It is impossible to establish a secure connection” in the Yandex browser. This is typical even for trusted resources: YouTube, Vkontakte, Sberbank and others.

Reasons for "NET::ERR_CERT_AUTHORITY_INVALID"

Not much can be said about the reasons; we will only note the possibility of problems due to SSL certificates, which sites must provide for display in browser windows. For various reasons, they are simply not detected or ignored by the system. Also, the browser often monitors the chain of connections, and if it finds an unverified DNS node with a possible information leak, the connection is also blocked. The same notification occurs when using proxy servers and VPN connections.

Block “Unable to establish a secure connection”

This blocking is especially common on cybercriminals’ web resources that lack an https certificate and require users to enter personal data or use online banking.

How to bypass the blocking

We have collected several proven solutions that will help correct this situation in Yandex Browser. Let's start the description with the simplest methods and gradually move on to more complex ones.

HTTPS/SLL protocols


Attention, such actions jeopardize the security of your personal data, so as soon as possible, put everything back as soon as possible.

Browser versions

Earlier versions of the Yandex browser are more relaxed about security: the error “Unable to establish a secure connection” occurs much less frequently in them. Switch to using them. When a site is blocked in them, the resource still becomes available through the “Advanced” item in the same warning.

Protection

The latest versions of the Yandex browser have many third-party anti-advertising add-ons (Protect technology) built in by default: Antishock, Adguard and others. They are located in Settings - Add-ons. Disable them all by moving the slider to the left. For better reliability, also turn off your antivirus program for a while.

Most add-ons and extensions are developed, to put it mildly, not by professionals, and sometimes even by criminals. With a large number of such extensions, the system begins to overload, which leads to various failures. If possible, remove most of them, because, most likely, you have not used some of them for a long time.

Cookie

Cookies have always become a problem when used for a long time. Each user must delete them from time to time, otherwise bugs cannot be avoided. Go to Browser History – Clear. Check the boxes next to the first four options. This will help significantly reduce the risk of new problems with “NET::ERR_CERT_AUTHORITY_INVALID”.

Recovery

If your PC is configured for system recovery, then use a restore point to go back a few days. Windows will delete all changes made by the user, but before that, uninstall the Yandex browser from your PC. Erase any information on the computer about its operation.

Other, less popular solutions

  • Updating or reinstalling the browser;
  • Checking the current time on your PC;
  • Enter your site through a search engine, rather than trying to get to it through a bookmark;
  • There may be some problems on the resource itself, which makes it closed to all users;
  • “Hijacker viruses” – you should definitely check for their presence on your hard drive using AdwCleaner, UnHackMe.
  • Finally, let’s mention the “Report a problem” function, which is located in “Advanced”. Let Yandex specialists help you.

Hi all! Sometimes when surfing the World Wide Web a warning appears in your browser: “ Your connection is not secure and attackers may try to steal your data..." If a similar error appears in your browser, do not worry, this is not a hacker attack, there is simply a problem with the certificate of a certain resource or resources. In most cases, such a warning appears due to failures in the client equipment, and not in the server part.

Below we will look at the reasons for the error “Your connection is not secure...” and methods for eliminating them. By the way, such a window can only pop up in browsers created on the Chromium engine by Google. The most famous browsers on this engine: Google Chrome, Orbitum, Opera, Yandex.Browser, Epic Browser, Titan Browser, Sputnik, Amigo, etc. So, let's find out what can lead to the above error and how you can fix it.

1. The system time is incorrect

If you see the error code Net::ERR_CERT_DATE_INVALID, this indicates that the wrong time is displayed on the computer. To fix this, you need to adjust the system time. Right-click on the clock on the right side of the taskbar and select “Set date and time.”


Next, click “Change time and date” and change the time, date and year. Now all that remains is to save the changes and open the same site, where an error about a secure connection pops up. If you often lose time, then the problem is probably a dead CR2032 battery, which is located on the motherboard. If it sits down, every time you turn on the computer, the CMOS parameters are reset and sometimes you need to press the F1 key when the message “Press F1 to continue, DEL to enter setup” appears. After replacing the battery, set the correct time and the problem will be solved.

2. Extensions that can block sites

After installing some antiviruses on your computer, additional extensions are embedded in the browser for maximum protection against malware. Due to such extensions, the error “your connection is not secure and attackers may be trying to steal your data” may also pop up. Typically, such extensions are installed along with antiviruses Avast, Kaspersky Antivirus, etc. If errors with certificates often appear, you can disable such an extension in the browser.

To disable an extension in Google Chrome, go to Menu – “Additional tools” – “Extensions”.


Next, we look for our antivirus module and then disable it by unchecking the corresponding checkbox. Restart the browser and check the site again.

3. Outdated or unverified certificate

If the site uses a certificate that is not verified by the publisher, then a similar error may also appear. It is not difficult for the administration of any resource to create a certificate, however, if there is no data, then naturally Chrome begins to issue a warning “ Your connection is not secure" Most browsers always check for the presence of a certificate, and if this is the problem, then simply click on the “Advanced” - “Go to site” item.

4. The problem is in the browser itself

If all else fails, you can alternatively reinstall the Google Chrome browser completely. This method has helped many people, so I couldn’t help but recommend it to you. The reinstallation process is very simple. First, you need to remove the current version of your browser. To do this, go to the Control Panel.


Here we select the “Programs and Features” section.


Next, find the Chrome browser in the list and click “Delete”.


After completely removing the browser, restart your computer, download it from the official Chrome page and install it. After such actions, in most cases the “connection is not secure” warning will no longer bother you.

5. Outdated version of the Windows operating system

If you are the owner of an old Windows XP, then you should not be surprised that various errors appear. Many developers have long refused to support their Windows XP programs, including Google. If you have SP2 installed, then I advise you to update your system to SP3. This is for those who fell in love with Windows XP and can't let it go. For everyone else, I recommend installing Windows 7 or even Windows 10, friends, you need to keep up with the times.

All the methods described above are aimed at ensuring that the “Your connection is not secure” error does not bother you anymore. Thank you for your attention!
