ERR_INSECURE_RESPONSE: what is this error and how to fix it?

Windows-systems, as noted by many users, are not immune from errors. One of these is the receipt and notification type ERR_INSECURE_RESPONSE. What this error is, not everyone knows. But it's quite easy to eliminate the problem. It is enough to follow the instructions below, which, by the way, can be useful in other cases when the operating system refuses to work.

ERR_INSECURE_RESPONSE: what is this error?

The nature of the failure is that there is an error requesting the server from the user terminal. If you look at the most common translation of the term, you can figure out that this is an internal problem.

At least this is evidenced by INSECURE, which is an exclusively internal security service. The fact that it does not respond signals the word RESPONSE. Thus, an error message is displayed indicating the line ERR_INSECURE_RESPONSE. What this error is, more or less clear. Now let's see how to fix it.

Failure and the main reasons for its appearance

It is believed that the main reason for the occurrence of such a problem is the main one is to use a half-duplex connection in the network, when communication is carried out, so to speak, over the TCP protocol.

On the other hand, if you have dedicated hosting, the browser can also block the entry to it. This is due to an invalid certificate. But the biggest problem is that the user PC can be blocked in the absence of such a certificate.

ERR_INSECURE_RESPONSE: how do I fix the error?

Now directly on how to fix the problem. Consider the algorithm of actions for the example of the Yandex browser. For it, you need to run the Certificate Import Wizard.

After that, you will need to use the function to save the file in the CRT format (by default, you are offered saving to the "Desktop"). Then you just need to reload the page. The certificate will be attached automatically.

But even here the solution suggested above can not help, and the problem will appear again as an ERR_INSECURE_RESPONSE message. What is this error in this case? A failure can be associated with the certificate validation service in Windows. But it's worth it to turn it off. This is done simply. However, when the service itself and the process associated with it are terminated, it is desirable to use the "Task Manager", which terminates the work of all applications that are related to the main service in one way or another. Of course, to deactivate all these processes, you can use both the command line and the shell of Windows Shell, but this is not necessary, although this method looks much more preferable.
