Thanks to all i fixed with restart router and again port forwarding.

Thanks.

Anyone?

I was try, i do all like lfs manual but again same error. Before 1 year we played normal, just create server then join. But now.... i dont know what is happening.

You mean Firewall > Advanced >select network Settings then there to add or in router settings port forward? If no can you explain me how to allow the port?

Thanks.

Hello, i want to play lfs with my friends but i can't.
I create a server directly from game but when they try to come in it says "ClientConnection:connection failed".

I tried with dedicated server but same error.

What to do to fix that?
Thanks.
