I have a FastAPI project which uses uvicorn server to run my application. speechsdk is used for Speech-to-Text operations, the endpoint I am using is "wss://eastus.stt.speech.microsoft.com/speech/recognition/conversation/cognitiveservices/v1?language=en-US", I had a runtime error which was this: "

 Runtime error: Failed to initialize platform (azure-c-shared). Error: 2153

I noticed I was using Ubuntu 22.04 LTS on my ec2. I followed the steps on: https://learn.microsoft.com/en-us/azure/ai-services/speech-service/quickstarts/setup-platform

I encountered this error:

CancellationDetails(reason=CancellationReason.Error, error_details="Connection failed (no connection to the remote host). Internal error: 1. Error details: Failed with error: WS_OPEN_ERROR_UNDERLYING_IO_OPEN_FAILED

wss://eastus.stt.speech.microsoft.com/speech/recognition/conversation/cognitiveservices/v1?language=en-US

After enabling the azure logs the error logs show:

[586746]: 34602ms SPX_TRACE_ERROR: AZ_LOG_ERROR: tlsio_openssl.c:691 error:1416F086:SSL routines:tls_process_server_certificate:certificate verify failed

[586746]: 34602ms SPX_TRACE_ERROR: AZ_LOG_ERROR: tlsio_openssl.c:2441 FORCE-Closing tlsio instance.

Also, my application uses a SSL certificate by LetsEncrypt and the .pem files are saved in a folder inside my application directory

I tried changing the SSL_CERT_DIR to several directories but still didn't work:

export SSL_CERT_DIR=/usr/lib/ssl/certs

Any help is appreciated!!!

    Hello @CRAZY INDIAN , Thanks for using Microsoft Q&A Platform.

    Sorry to hear about your inconveniences. Firstly, if you haven't, please try to add SDK logging to check if any additional details can be seen in logs? There are similar kind of issues here please check if that helps you. Otherwise, I would suggest raising this issue here so that the SDK team will help you in advising what could be wrong in your case: https://github.com/Azure-Samples/cognitive-services-speech-sdk/issues

    I hope this helps.

    Regards,
    Vasavi
