Speech Sdk SpeakTextAsync returns error 502, 504 or connect ETIMEDOUT 20.189.108.64:443

Question

My program uses microsoft-cognitiveservices-speech-sdk 1.16.0 and uses SpeechSynthesizer.speakTextAsync for text-to-speech service.

It has been working for several months without any issue, until now it suddenly returns error 502, 504 or connect ETIMEDOUT 20.189.108.64:443.

What should I do?

Answer 1

Hello,

Thanks for reaching out to us. Error 502 and ETIMEOUT seems a issue due to DNS. 504 is reflecting internet connection issue. I will suggest you check your internet and DNS setting first then try below:

Restart your computer and networking equipment.
Clear your cache and cookies.
Change your DNS server.

Hope this helps.
