I’m experiencing a really weird connection issue that I’m afraid if it’s related to some security breach.
I can access to any websites so far EXCEPT Stackoverflow. It is particularly weird because when I reboot the PC, it works initially and I can normally connect to the site. However if some time pass, like 20 min or so, Chrome and other browsers warn that Stackoverflow’s certificate date is invalid.
As you can see in the above screenshot I attached, the current date is displayed correctly but the expiration date is more than 2 weeks ago.
What’s happening here? I called all my friends but they say they have no problem accessing Stackoverflow so I’m assuming that it’s the problem on my end. However, it is still weird because the error is apparently because Stackoverflow’s certificate is outdated – ONLY for me.
What’s going on here? Is this a sign of some kind of a security breach?
