Same for me EDIT:i have recently reconfigured my router, and i forgot to forward assaultcube_server ports.

PS: If you are using a router you'll have to forward your ports.
Create a rule in your firewall.

Yes, read here:

I think you'll have to use different ports for 1.1, in which case you should consult the documentation.
