After last update I can't start hero testing or join any serv that doesn't have any real players. I can join hero testing in party with my friends. I thought smth with game files, I checked them but everything is good. So how can I fix dat?
I had the same problem. It turns out my Palworld server was using the same query port.
My guess is that you're operating some sort of dedicated server. You'll have to find out how to change the query port for your server specifically. This is the link I used to change the query port for Palworld, but it'll probably be different depending on which type of server you're hosting.
