Hey everyone, my friends and I run a small vanilla server for just us and we encountered this issue. No one could log in without being disconnected with that error code. I had my friend that ran the server go into single player and teleport his character far away from where he was. When he loaded the world again on the multiplayer server he was able to play without being disconnected. After he teleported back to our houses he jokingly said "I bet its all these cows we have." I just laughed and told him to kill all of them incase it was. It fucking worked. After he killed all of our livestock we were able to log back on to the server. My theory is that we hit some sort of entity cap or some shit and the game just didn't know what to do so it disconnected us. We had like maybe 100 cows and 50 sheep in a 30x27 pen. Not sure if this is any help for you guys but it worked for us.
