Connection problem between two users in a UEProject with GameLift – Amazon GameLift

Hi guys, good morning!
I’m having a problem and I’m confused…
When I’m trying to connect two users in a dedicated server from my build project, the message sended from amazon is this:

However, after a few seconds, it returns me to the join the game screen instead of traveling to the third person example map.

I went to the virtual machine to see the logs and this is what returns it…

When I made all this sequence, my game sessions are created, so I have to delete modifying scaling parameters of my fleet

Btw, you look that? 2 player sessions has been created and can’t use them… I don’t understand what’s happening…
