Why can't i test multiplayer with a friend using the editor?

Hello i have a multiplayer project that i’m working on and i wanted a quick way to test the multiplayer with my team using the editor directly instead of a compiled exe. I was trying out CouchKnights and it says on the level:

1) Host launches with UE4Editor.exe CouchKnights Room?Listen -Game
2) Client launches with UE4Editor.exe CouchKnights  -Game

I tried this using this (using the uproject full path instead of just CouchKnights) and i’m able to host, but my friends can’t connect. If i do it locally and connect to 127.0.0.1 or my public ip it works. I think i read that the open console command does not work in the editor, does that apply when running the editor in -Game mode? Thank you.

have you opened the port 7777? maybe it blocks you friend out.

Yes it’s opened, i think otherwise connecting to my external ip wouldn’t work
