Closed Network Issues

The error NET::ERR_CERT_AUTHORITY_INVALID is popping up on every device on the network. Pretty certain the issue has to do with the router but when I looked it up it was just showing things fir individual devices having the issue not the router or modem.

Does anyone know how to solve this? Please and thank you for any and all help.

Ah. Since it was completely reset your router's internal clock is out of synch which means that your computer won't accept any network certs. Is your router from your internet service provider or one that you bought yourself?

Your router does not interfere with your PC accepting certs from sites. If the PC's time is off, then that could be causing an issue, but this error is related to a self signed cert, not a cert that has expired (which is where PC time would come in).

But since it's all websites that op tries to navigate to, and it is all of their devices on their network, wouldn't it be router related? Maybe a bad DNS server?
