I have recently a problem to access to sites https in all browsers. In the past I had a similar situation and that the problem was solved by removing Bytedefender.
Now, I have no antivirus, Windows security only, and there is an app called Lenovo VANTAGE in which the wifi security is disabled.

I use Windows 10 and the firewall works.

I googled many posts on the web and didn't reach how to repair my problem.

My access to Internet is by hotspot by my phone.


An example of message when I try to click a site is

Secure Connection Failed

An error occurred during a connection to www.dropbox.com. PR_CONNECT_RESET_ERROR

The page you are trying to view cannot be shown because the authenticity of the received data could not be verified.
