[Bug] HTTP 503 Service Unavailable - previously working, config unchanged, network OK

[Yangjinyao11]

I am getting a persistent 503 Service Unavailable error when making speech requests using the Wit.ai Unity SDK.

The system was working normally two days ago. Today, without any code or configuration changes, it started failing consistently.

Error log：[VSDK] [SpeechService] [BaseSpeechService.cs:271] Request Failed
HTTP Error 503: System.Net.WebException: The remote server returned an error: (503) Service Unavailable.

What I have tried:

Switched to mobile hotspot (same error)

Ping api.wit.ai successfully (0% loss)

Regenerated Client Access Token

is this a known service-side issue? Any help would be appreciated.

Getting the exact same issue.

I did nothing and it returned to normal the next day.
