Factorio Forums

Hello there, again!

I want to connect with a friends multiplayer game that i could join some weeks ago fine but now it suddenly doesnt works. I tried everything from portforwarding to disappling the firewall and the antivirus and even changing the NAT type but nothing worked. I literally found NOTHING similar somewhere in the internet and i am really helpless as i tried everything humanly possible considering networking. Other friends can join his game fine without doing anything trough factorio and steam directly. I have no idea what to do next.

Help is appreciated! Best Regards
Semthepro

PS:[This is a technical problem, so it cant be off-topic]

I posted the wrong link before...
The error message means that you did not receive a confirmation message from the server, post the logs of server and client of the same session for further info, see my signature.

I'm having the same issue, updated factorio, deleted old saves, ported router, what did I miss?
Here is the log
"ip addy was changed"
thanks for any help
