Can't see client between dedicated server mode

I have a project where I already could watch each other client in firstperson BP (as the first image)


So after that, I started creating a new level where I created my project, but when I begin all the process to make the dedicated server and run my app, the clients are not getting connected, in the following image I change the floor but in the other app the floor keeps its floor.


The only weird thing is that, in the second image, when I run the server I get the following warnings, so I think that is the problem but I’m not a developer so I would appreciate any suggestions in order to check what I have to check


Ok, In multiplayer the server has authority over all replicated actors except for Player pawns. Each player has authority over its own pawn. That was the problem!!

How did you fix it then…
