This Connection is Not Private

I’ve been getting the “This Connection is Not Private” error message on safari, I can usually fix it by forgetting my network and restarting, but every couple hours it will start up again, it also makes apps like steam and outlook crash.

I’ve checked my date and time, cleared my browser data, changed my DNS, and my certificate is fine. I’m using my college’s student WiFi and no one else is having this issue. Any suggestion would be greatly appreciated.
