I can't log in to Project zomboid multiplayer.

I've been having this problem all day, I have a host server, and every time I try to enter the game I get an ERROR 1 and the game keeps loading. I have already reinstalled the server, disabled the mods and also reinstalled my game, I have even tried to enter another server, but it keeps giving me the same problem.

Can you start a single player game?

 

Delete "mods" folder in "C:\Users\YourUserName\Zomboid"  then Verify the game  (In Steam Library RMC Project Zomboid > Select "Properties" > "Local files" > "Verify integrity of game files").
