Or you know.. the entire multiplayer system in general is just completely broken as f--- right now and expect it to not work at all when you use it. Just wait for servers. That should fix 90% of this. This is an unfinished / work in progress / early access game, even the normal version of it. You should stop ever using the word "Server" when you refer to multiplayer in satisfactory. There are no servers at the moment. Right now we have Host, and Client.
