I have an issue where for months I am unable to log in through the main page (Upper right "Sign in"). First it was intermittent, now permanent. The solution for me is to not log in from roll20.net homepage, instead click "Play Now" or "Join a Game" in the upper left, then sign in. Cache, cookies, browsers did not fix the issue. Even built a new computer and still a broken login from the 'Sign in' on the home page for me. Good luck. Hope your group gets to play.
