I still had trouble with it - but google was remembering my old login details so I clicked the other login button and now I am in, not even sure which way I am signed in. I never signed up for an actual account - but on friday I think the GH login worked from work (where I am now). So maybe GH worked on Friday and then broke? it sure didn’t work from home over the weekend, and if I log out and then try to login with the GH link it gives the error.
