Permanently disabled from connecting to a game, server-side issue.

First time I've ever seen this bug. Unable to connect to the game I am, at the time of posting, currently in due to some error claiming I have no network connection. Based on that nothing on my PC has changed in the last day since I played, this is definitely a server-side issue. I've tried 20 times to connect now, same popup every time after 30 seconds. Retry simply gives the same popup after another few moments. I am forced to stay out of the game no matter what.

Nothing to do for it now, posting this in hopes that - if the issue continues - there will be a fix. Otherwise, I'd much appreciate having leaverbuster leave me alone for a forced leave that isn't my fault.
