Before asking this question, I have already tried all of your proposals, unfortunately, this problem still exists. And what's worse, as before it was only on server simulation 1 , now it started to appear also on simulation 2 (I couldn't connect even when there were only 2000 people). Fortunately, on the server simulation 3 is still
easy. From what I have been able to read in similar discussions, the problem may also be related to the multiplayer mode itself. I'll wait for updates. Thanks for wanting to :)
