Error that happened right before:
-It only happened after steam said cloud out of sync. On both computers.
-I tried a vpn
-I tried logging out of factorio
-I checked file integrity of the game
-I tried deleting my save states
-I tried disabling steam cloud
-I tried the "trick" of starting a multiplayer game to "open the port" and then switch games.
-I can join some other publics, but not all (?)
-It says "Connecting to server" then gives that error. It does not even prompt to sync mods. (I even deleted mods to see if that would fix it)
-i disabled antivirus
Ive been playing on this server for 200 hours. No issues. Then randomly this. Nothing happened. Nothing has changed. didnt mess with the router, or antivirus or nothing. Literally working like 10 hours ago, and not now. :'(
Did so much googling, noone has a solution to this error....
EDIT: Solved; Portforwarding issue on server side
