When you call the PlayFabClientAPI.LoginWithCustomID function,
ServiceUnavailable /Client/LoginWithCustomID: HTTP/1.1 504 Gateway Timeout
An error occurs.
Sorry for the inconvenient, this issue could be related to the recent incidents : PlayFab Status - Some titles are experiencing high latency and 500 errors. Currently, this issue has been resolved, and this login API works fine in my tests. If your problem persists, please let us know.
