j’a
I solved the issue on my side.
What worked:
-
Removed all mods (even disabled ones)
-
Deleted Steam launch options:
-nomovie -dev -
Ran (as Admin):
netsh winsock reset netsh int ip reset ipconfig /flushdns
After rebooting, multiplayer worked again.
In my case, it was related to modding/dev mode.
Hope this helps.
