[help]Instantiate only working locally

I am really desperate, I wasted so much time trying to solve this.
Basically at start everything worked, I had 2 players with another client and it connected and spawned, then I added a lot of other code, and now when I test it everything spawn only locally for some reason.

I know it may be hard without code but really the network code is nothing, I just spawn with PhotonNetwork.Instantiate, and there is nothing else, the rest of the code is too much to post but also irrelevant.

Is there any potential reason for this to happen? Some setting in photonview, or the lobby, I don't know
