Happening to me too. one of my players can get in just fine, but i and another player got 503 errors on the main roll20 page, and when we tried to load our game, it's stuck on the black "Loading..." message and never going anywhere.
Hi everyone! The Firebase servers are currently recovering from the outage-- however play should be unaffected during this time. <a href="https://status.firebase.google.com/incident/Realtime%20Database/18058" rel="nofollow">https://status.firebase.google.com/incident/Realtime%20Database/18058</a> Thank you for your patience, and sorry for the trouble!
I am also having the same issue when I start the online playing. It will occur after a new purchase of Linksys WRT1900AC AC1900 Dual-Band Wi-Fi Router. Always I am getting no internet connection. but when I try to use other apps so it was running. I already contact my Linksys router support executive and he said router will ok. So why I am getting this when I load the game.
