    Hi @MohamedAhmed,

    Thank you for choosing Photon!

    There already similar reports here and we're looking into this.

    Does this happen on Editor?
    Are you building for Android?
    If you can switch Scripting Backend to IL2CPP or Mono version to 3.5 and try again I think that would solve it.

    EDIT: I misread the error message.

    This problem happen because of the internet company , i tryed to use VPN and it work very good

    But this problem fix to me only, if i share this game the same Error will happen or no ?
  • Im facing a similar problem.
    Sometimes even after login, and "Connected to Lobby" callback, I cant create a room => "not connected to master". Also after leaving a room (changing scene).

    Fallback cases to reconnect in these situations help, but sometimes a reconnect is necessary.

    Latest Photon v2 version
    Unity 2019.1

    Didn't tried to change to ilcpp.
