I also had the same problem with Chrome and also with Microsoft Edge, it would be interesting to log in, but there seems to be a problem, a security and invalid certificates
I've ignored those warnings in the past and never had an issue with it, but I'm being a bit more cautious when I keep reading about big name companies being compromised all the time. If everyone else is going there and it's not an issue, it's probably OK. The fact that you're seeing the same warnings with Edge and Chrome (both of which are on this machine but that I rarely use), but Trevor doesn't get the warning is odd.
