Create Channel always fails with ResourceNotFound Exception

I can confirm that the credentials work with webrtc-sdk-c used with freertos example here.. It doesn't throw any error.

Below are the error logs from the test page.

[2023-07-25T10:18:41.906Z] [INFO] [CREATE_SIGNALING_CHANNEL] Attempting to create signaling channel with name ScaryTestChannel
[2023-07-25T10:18:42.866Z] [ERROR] [CREATE_SIGNALING_CHANNEL] Encountered error: {
  "message": "Not Found",

}

Boot up logs from my ESP-WROVER-KIT, suggest that it is working as expected:

Any help is appreciated.
