Hi i have try to fix this issue, but i did check my ports and it’s says (Port closed on everyone, even if I have turned off firewall, fixed inbound/outbound 30120 port and start server, but still nobody can join.

How can I solve this?

Are you accessing your actual router to port forward, or are you only doing this through the firewall?

I have acces to my router and have set up a portforward in there, and use Tcp/udp, also turned off my firewall and setup an inbound/outbound for Tcp/udp 30120

Do you have a port triggering section in your router settings?
