UpdateUserData fails with ServiceUnavailable - 'Unknown Error', 400 BadRequest

I'm getting this Unknown Error when calling UpdateUserData from a Unity build on Android. I'm able to make several successful calls before this happens (I'm calling it roughly once a minute). I never encounter this error in the Unity editor, only ever on Android (not tested on iOS), so it can't be a problem with the request. When I call it again the next time it works. So it's just failing for no apparent reason maybe 1 in 10 attempts.

HttpCode: 400

HttpStatus: BadRequest

Edit: Should probably also point out that this is on wifi and connected to the same network that I'm connected to in the editor with no problems.

Try changing what request method PF uses (check in PF editor extensions in Unity), try setting it to UnityWebRequest or HTTPWebRequest

I was already using UnityWebRequest. I tried switching to HTTPWebRequest but it had the same problem.

Anyone got any other suggestions? Is this just a PlayFab bug that I have to live with?

I've had similar scenarios with Unity games not being able to make any kind of web request, and reporting 'Unknown Error'. Here's what I did in each scenario to fix it:

Linux: Install cURL

Xbox: Go to any webpage in internet browser and reboot

Android: In Player Settings (in Unity), make sure 'Internet Access' is set to Required
