IntentRecognizer not working with LUIS WestEurope app

Describe the bug I tried to use IntentRecognizer with a LUIS app, hosted in WestEurope (https://eu.luis.ai). I started with the samples and was quickly blocked with this IntentRecognizer, where when I send an audio (from audio file for example), the text is well transcribed but then nothing happened about recognition. I just got a canceled event after a long time:

Say something...

    Session started event.
RECOGNIZING: Text=tell
RECOGNIZING: Text=current
RECOGNIZING: Text=current weather
CANCELED: Reason=Error
CANCELED: ErrorCode=ConnectionFailure
CANCELED: ErrorDetails=WebSocket operation failed. Internal error: 3. Error details: WS_ERROR_UNDERLYING_IO_ERROR
CANCELED: Did you update the subscription info?

Recognition done.

I used exactly the same application on LUIS West US portal (https://www.luis.ai), changing LUIS Subscription key, LUIS App Id and LUIS region, and it is working well:

Say something...

    Session started event.
RECOGNIZING: Text=tell
RECOGNIZING: Text=current
RECOGNIZING: Text=current weather
RECOGNIZED: Text=Current weather.
    Intent Id: Weather.GetCondition.
    Language Understanding JSON: {
  "query": "current weather",
  "topScoringIntent": {
    "intent": "Weather.GetCondition",
    "score": 0.9494868
  },
  "entities": []
}.
NOMATCH: Speech could not be recognized.
NOMATCH: Speech could not be recognized.
CANCELED: Reason=EndOfStream

    Session stopped event.

Stop recognition.

Recognition done.

In both cases, I used subscription keys of type S0 (not free), apps are targeting English and Speech is enabled in LUIS settings.

Capture (1st call: West US, 2nd call: West Europe):

To Reproduce Steps to reproduce the behavior:

1. Create an app in LUIS WestEurope, which language will be English
2. Add a pre-built domain intent for example, like Weather.GetCondition
3. Add Speech capability in LUIS settings
4. Train and publish.
5. Use IntentRecognitionSamples in this repository

Expected behavior IntentRecognizer should return the same thing between WestUs and WestEurope

This should be fixed from the service side this week. I’ll give an update once the fix is deployed. Thanks for your patience,
