Unable to start avatar

Hello Team,

I am referring https://github.com/Azure/gen-cv/tree/main/avatar/interactive link to create talking avatar. I entered Key, zone everything in-place. API is running fine.

**Error message**
```
[2024-07-19T10:38:16.188Z] Unable to start avatar. Result ID: 33D085E9753B4F1D83F3009652A4B098
main.js:137 Unable to contact server. StatusCode: 1006,

startAvatarAsync2 :{"privResultId":"33D085E9753B4F1D83F3009652A4B098","privReason":1,"privErrorDetails":"Unable to contact server.

```

Start with the avatar/interactive example and inspect main.js around line 137, where the connection failure is reported. Reproduce the setup using the provided westus2 Speech websocket error and verify the configured key and zone. Done means the avatar starts successfully without the 1006 connection failure.
