Potential Security Error, occurs on many sites but not all.
I went to work and when I returned a new router was installed and ever since I get errors on almost all sites I visit. It is the potential security issue, requires secure connection and when I look into the info it says the certificate is being denied because it is self signed. And anytime I go to hit learn more I receive a 400 error and cannot continue. I am also unable to update apps I have on my pc or connect to the internet using anything besides a browser. I get the same kind of error on edge as well as Firefox.
I have already set things up so I am using no proxy and I do not have https only mode enabled.
The only constant is that I can open YouTube and watch videos. I thought this meant it was a dns issue but I have tried several fixes for dns issues and they didn't work.
I would attach photos of the error but Mozilla is also unable to open due to the errors so I'm filling this out on mobile.

How is this a Firefox browser issue? That sounds more like your Router or ISP issues.
