I followed the instruction https://learn.microsoft.com/zh-cn/azure/ai-services/speech-service/troubleshooting?tabs=curl#connection-closed-or-timeout

there is a error in validating your resource key.

I am sure that I input correct speech_key and speech_region, however, it still occurs the bug.

@yulin-li could you please help to take a look?

WS_OPEN_ERROR_UNDERLYING_IO_OPEN_FAILED is the connection issue. And looks that it's an SSL issue. Maybe you can check e.g., if TLS 1.2 is enabled in your machine; if the system clock right; if you are using proxy that modified the cert.

The endpoint is right from the error message, and key authentication is after the underlying connection established.
