Desperately Seeking a Solution to Google Hangouts Errors 212, 213, 214, 215, 216

Google Hangouts ErrorI’m a huge Google Hangouts user. It’s typically a multi-day occurrence that I’m on a hangout and one of the devices connected to the mega-video-conferencing setup in my office is a Chromebox.

A few months ago I got Google Hangouts errors intermittently for a few weeks but it magically cleared up. I noticed it again on Sunday and it has been constant on all my computers in multiple locations on different networks.

I’ve tried clearing the cache, logging out, and resetting the browser / computer, which seems to be the only constructive¬†solutions I can find on the web. The other solutions, that are not so constructive, are “wait for a while for it to clear up” and “use something different.”

Strangely, this problem only exists in Chrome. My iOS Hangouts works fine as does my Chromebox.

Does anyone have a clue how to solve this nagging problem? The screen shot I’m getting in Chrome when Gmail is open is on the left.
