So when a I connect to a vpn from my computer, I can just manually tell the browser that I don't care about the outdated / mismatched cert and connect anyway.

When I connect from my Nvidia Shield, it won't connect and I am not sure if that is the issue causing it to get stuck or not. Here is the log (i replaced the IP with X.X.X.X for privacy reasons:
