Service Unavailable: PreconditionFailed

After I update my Unity SDK to Version: 0.31.160705.
When called any login command. I'll got a errorcallback saying:
"HttpCode":412,"HttpStatus":"Service Unavailable: PreconditionFailed","Error":1 ......

Here is my test code:

LoginWithPlayFabRequestrequest=newLoginWithPlayFabRequest();

request.TitleId=titleId;
request.Username="ethan012";
request.Password="ethan012";

PlayFabClientAPI.LoginWithPlayFab(request,OnLoginCallback,OnErrorCallback);

error result json:

{
                
    "HttpCode": 412, 
    "HttpStatus": "Service Unavailable: PreconditionFailed", 
    "Error": 1, 
    "ErrorMessage": "{\"code\":200,\"status\":\"OK\",\"data\":{\"SessionTicket\":\"67529B907D4E74A-0-0-D84D-8D3A652B5625930-FAC2D54BECE2AA6A.B95E6372887239D3\",\"PlayFabId\":\"67529B907D4E74A\",\"NewlyCreated\":false,\"SettingsForUser\":{\"NeedsAttribution\":false},\"LastLoginTime\":\"2016-07-07T10:15:58.291Z\"}}", 
    "ErrorDetails": null, 
    "CustomData": null
}

Please consult the Release Notes to help you upgrade. The "Upgrade Warning" notes in red should address any issues you have. If you have other issues, please put them into a new thread, so we don't overload this one.

Please update your sdk, and set PlayFabSettings.CompressApiData = false; when you set your titleId.

We tried to launch compression with the last update, but apparently we didn't handle all possible code paths.

The 412 error is an odd one - it implies that there was a precondition specified which wasn't valid. Also, the information in the ErrorMessage is actually the good response to logging in, so the call looks like it succeeded and returned a 200. Can you try this call in Postman to see what results you get? Can you get a wireshark or netmon capture of this call from your game?

Postman works well.

----------------------------

POST /Client/LoginWithPlayFab HTTP/1.1 Host: D84D.playfabapi.com Content-Type: application/json Cache-Control: no-cache Postman-Token: 811b092d-3dc0-e462-ff82-9143df0376e3 { "TitleId": "D84D", "Username": "ethan012", "Password": "ethan012" }

----------------------------

{ "code": 200, "status": "OK", "data": { "SessionTicket": "67529B907D4E74A-0-0-D84D-8D3A6D0C500F29F-A6C67700185E8965.DDD828C11D2D80DB", "PlayFabId": "67529B907D4E74A", "NewlyCreated": false, "SettingsForUser": { "NeedsAttribution": false }, "LastLoginTime": "2016-07-08T01:38:12.155Z" } }
