How to fix 60 SSL (photo)

Hello, I am facing a problem. Previously, it was working since yesterday. The problem started. I tried it Gnome and Kde And the same problem

in which country are you?

Saudi Arabia

I formatted the system and the same problem

you should probably have a look at that certificate, this screams MITM attack, might be your country/isp trying to spy on you, could be someone else.

Is there a way to find out?
Note that I use DNS for a router

I would think so, but I’m not sure, if this is the best forum to try to dissect your connection. Personally, I would have to read up on that.

The problem has been solved. I moved to Fedora and it works without problems. I wanted to try it and went back to Debian KDE and it works. I don’t know what I did.
