In my server list, numerous servers are displayed as offline, even though they are not. I have to use a different domain everywhere to be able to join these servers. When I try to join, I get the message “connection timed out: getsockopt.” However, I don't have this problem with the normal Vanilla client, where I can join normally via all domains.
Examples are:
timolia.de -> Must use play.timolia.de
hypixel.net -> Must use mc.hypixel.net

I have already changed my DNS settings on the advice of support and reinstalled the game, but that didn't help.
