Hosting server on PC1 and joining on PC2

I’ve implement a basic online system using the Create Session, Join Session, Find Session nodes, I’ve tried it on the same computer and I’ve joined the other player’s server successfully.
Now I’m trying to do the same on 2 different computers, I’ve packaged the project and sent it to PC2, but PC2 cannot seem to connect to the server on PC1.
I would consider myself new to UE5 and the whole networking thing, any help would be super apperciated :wink:
