Connection Error

Options
This error started happening suddenly,

when im trying to connect to the Photon servers from the unity editor alone, it connects normaly.

but when im creating a build of my game and trying to connect from Both of the game instances, it connects from the build, but the editor wouldn't connect, and send me this error:

OperationResponse 230: ReturnCode: -3 (Already authenticating). Parameters: {} Server: NameServer Address: ns.exitgames.com:5058
UnityEngine.Debug:LogError(Object)

Im just using a start funcion that has an PhotonNetwork.ConnectUsingSettings();

it worked that way for a long time, but now it just wont work, any idea how to fix?
