Well, I was on a server the other day, and when I logged out and tried to join my server, it was saying "End of stream" every time I tried to log in after at least a 2 minute wait. It appeared, via my server console, that other people were having the same error. Then, after a while, it started to give me an error that was mostly gibberish (image below). At first I thought it was just me, because there were other people on my server. To prove this I shut the server down and reloaded it. When I opened it back up the console showed everybody losing connection when they tried to join, and nobody being let on the server.

I thought that was very odd, but then I noticed the servers that I play on having very few people on them as well (from people leaving and not being able to get back on), and when I tried to join them I got the EXACT SAME gibberish error I got before.

Help?
