A few of our users are experiencing issues when trying to log in via Steam.
The error they're getting is:
[ServiceUnavailable, Failed to receive data, 400 BadRequest]
This is for titleID: E79E
API Call: PlayFabClientAPI.LoginWithSteam
Been running them through the usual blind troubleshooting things, making sure they have the latest versions of Steam installed, making sure there's no overly restrictive firewall blocking the request etc. but nothing seems to be working for them.
Any idea what might be happening or how we could fix it?
Logging in works for most users, but this seems to be happening to a not-zero amount of players, so really want to hunt it down.
