Server Join glitch

This bug exists since months now and it didnt got fixed yet. When I want to join a server, sometimes when its loading the resources there comes the chest that usually shows that the game is saving. When I had it the first time I thought I could wait because Maybe its normal but whenever this chest pops up the game "saves" forever and I have to restart it. Maybe this happens a few times in a row until I finally can play the server.
