This has been happening intermittently for months, but almost constantly in the last couple of months. Whenever I try to launch Roll20 in Google Hangouts, I get the following error: The page at <a href="https://ega1ishctv8cj3blqun5vr891vinoa3n-a-hangou" rel="nofollow">https://ega1ishctv8cj3blqun5vr891vinoa3n-a-hangou</a>... says: Fatal error: Unable to retrieve authorization token. Please reload and try again. No matter how many times I reload, I get the same error. I use Firefox (latest version), have cleared the cache and restarted in safe mode in order to disable all extensions, and I still get the error. Curiously, this only seems to happen on the day of a scheduled session. If I launch Roll20 in Hangouts the night before a session, the app loads without issue.
