Hi, so I have been getting this error whenever I try to join one specific server. Any other server I join works fine. It'll go to 'Logging in..." for a good 10 - 20 seconds and then cut to that error. I have tried restarting my Minecraft launcher multiple times to no avail. Also, I have no means of contact to ask the server owner to do something about it to see if it's a problem on their end. Help please!
My server is having the same problem. We are getting this error when we try to log on to play. I'm doing searches online and it is coming up as being a minecraft bug that nobody can seem to figure out how to fix. ugh.
