Error running OpenAI Edge TTS & Open WebUI locally using Python

[sai-mike]

I am running both on my development PC which runs Debian 12. When I ask Open WebUI to 'Read Aloud', I get an error popup from Open WebUI and this is the terminal output:

` Edge TTS (Free Azure TTS) Replacement for OpenAI's TTS API

Forgot to add, I ran the curl example from https://github.com/travisvn/openai-edge-tts?tab=readme-ov-file#standard-audio-generation and it works fine.

Hmm. You might want to try using the local domain like 192.168.X.XX

Send a screenshot of your TTS settings page from Open WebUI and tell me how you're running Open WebUI (Docker or some other way)

And I might be able to help you diagnose this

Thanks. I just figured it out while getting the screenshot for you. https://github.com/travisvn/openai-edge-tts/?tab=readme-ov-file#open-webui clearly shows the Open WebUI URL as http:// and I entered it as https:// . Force of habit I guess. It is working correctly now with http:// .
