How to test a cooked game with Hamachi

I cooked my game and try to test multiplayer with a friend on Hamachi.

I am using Blueprint Online Session. It works well with 2 computers in my own network.

With Hamachi and our firewall turned off, the client can’t see the host.

Do we have to do something more to make it work ? Thanks

Would like to get answer aswell :stuck_out_tongue:
