I’m not sure if my internet was acting up yesterday, but after i logged into steam and was in the game, i was getting an error that my steam account was wrong while I was trying to log in. I was able to log in normally using my email.
There were points in time when I would be able to get in with steam, but then would either be disconnected due to a network error, or steam. I obviously would not see the steam error when logged in with my email. At one point the entire chat was dead, then people came back.
