myrouter.io vs 10.0.0.1 for XB8 modem

looks like the cert on the modem is hard coded for myrouter.io. As a result, I get hundreds of error windows on my windows PC in the morning because the cert isn't trusted, and something on windows is trying to access 10.0.0.1. When I go to 10.0.0.1 in my browser, I get the untrusted cert warning. I'm seen others here with the same issue. Even though the cert is valid for 6 more months (2-27-2027), because is locked to myrouter.io, the cert is not trusted.

I called Xfinity support and they said the XB8 isn't being updated anymore, so they are sending a newer XB10. 

Because Xfinity support people don't like to post solutions here (for some unknown reason), the solution seems to be to get a newer modem. Well see if this actually resolves the issue as they are shipping it to me.
