Unable to connect to the host. I want to play game with my friend!

Issue:
I wanted to play game with my friends, but if we open the room, we can’t join there.
However, we can join other rooms.
I checked my firewall and edited it
But the situation didn’t go well

I did not find anything wrong in your log file. Please wait for a moderator to assist.

The host needs to port forward correctly in their router. If you can’t do that, you can try like Hamachi which has worked for some.

how do you port forward correctly???
