Listen server with hamachi

HI,
I’m trying to modify the thirdperson project to be able to play with a friend in multiplayer using Hamachi.

I’m generating the exe by doing “package project” and on 2 PCs connected to the same hamachi network I’m launching the generated exe with a simple double click.
From PC 1 I press the button that starts the create session and open the original map of the example.
From PC 2, by doing “find session” I correctly find the session of player 1, but when I do join nothing happens even if it goes to success.

Did I forget to do something?

I can’t figure out how to make it work because if I duplicate the exe on my PC and launch them both I can successfully join the second one
