Online Mobile Game ( controller of player2 does not work )


Hi guys, I was creating a mobile game online,
when one person enters everything ok, the mobile controls work perfectly, but when the second person enters his mobile controller does not work, and clicking the jump button makes player1 do a mini jump (even if he does not move in his interface) , I'm afraid that the controller of the second takes the player camera of player 1 as render mode, so it doesn't work for the second one, I repeat that this is only a hypothesis.
Could you tell me what it could be and if there is a way to fix it?
Many thanks in advance
