Multiplayer Blueprint: In the clients, the camera roll is a little bit rotated compared to the server one

Hi guys, as the title suggests, in my multiplayer game when i play as a client the camera roll is a little bit rotated.
I attached some images to make you understand better.

Server:

Client:

I can’t understand where the problem is, in the character blueprint i don’t even touch camera rotation because i work with the aim offset system and only that is replicated.
Can anyone help me?
