Everything was working fine and then yesterday her landlord changed the cable modem and now this problem is occurring. We started by unplugging both the modem and router, waiting, plugging in the modem, waiting, and then plugging in the router. We restarted her computer and proceeded.Your connection is not private, blah, blah...(NET::ERR_CERT_COMMON_NAME_INVALID)
We double checked that the time is correct on her computer. We cleared the browser cache completely. She is only using Windows Defender for her virus scanner. The problem persists.
Any ideas? I'm trying to trouble shoot this from 1200 miles away.
Edit: The sites she is using to test for the issue are google.com and netflix.com
