We're (rarely) seeing the following error coming back from PlayFab. If it happens, it happens for a short period of time (~1 min? Less?), during which no Steam calls work. Can you guys investigate on your end?
The timeout must be set for ~1s, as we get the response almost immediately (or, that's part of the cause and something is borking a timeout somewhere)
