Hi, we are facing weird PlayFab connection problems in a Unity game. In our game, user logs in by calling PlayFabClientAPI.LoginWithCustomID with CreateAccount set to true and CustomId set to player-provided nickname.
Part of our players (as well as some developers) cannot access PlayFab. What I mean by that: 1) They cannot access https://developer.playfab.com/ in any browser, e.g. getting ERR_CONNECTION_TIMED_OUT in Google Chrome. It makes devteam unable to use the PlayFab dashboard. 2) They handle login failed delegate in-game with error report: "/Client/LoginWithCustomID: Request timeout" 3 minutes after the attempt.
Both of these problems are fixed for these users after turning on a VPN client. However it is not a satisfying solution - we cannot tell our players to use VPN every time they want to play our game.
It is not directly connected with any specific ISP. There are users using the same ISP and part of them can access everything normally, while the other part can't.
What can be causing such problems? We would love to provide some more details on our issue, but we don't see any rules here. How can we troubleshoot it further?
