Dify version

1.4.3

Cloud or Self Hosted

Self Hosted (Docker)

Steps to reproduce

I am running dify using Docker. I have configured the ChatTTS launched by Xinference in the configuration table of dify. However, when I try to play sound, It's not responding., and I cannot play any sound normally. When I look at the container logs, I see that an error is reported.Could you please tell me what the problem is and if there is a troubleshooting plan.

✔️ Expected Behavior

After the dedify app is published and I click the voice play button, I would like the sound to play correctly

❌ Actual Behavior

After the dify app is published, clicking the voice play button does not have any corresponding.

The "Response ended prematurely" error means Dify's TTS request to the ChatTTS/Xinference plugin daemon was unexpectedly cut off. This usually points to a problem on the plugin side or with the connection between Dify and the plugin daemon—not within Dify itself.

Here’s a focused troubleshooting plan:

  1. Check the logs for your ChatTTS/Xinference service for any errors, crashes, or warnings at the time of the failed request.
  2. Make sure the ChatTTS/Xinference service is running and healthy, and that Dify can reach it over the network.
  3. Double-check your Dify TTS configuration: ensure a valid voice is set and that TTS is enabled for your app. If no voice is available or configured, TTS will fail and can cause this error. Recent Dify updates improved voice handling and error messages for this case—if you can, try upgrading or backporting those fixes see PR #21821 and voice selection fix.
  4. Try a simple, short text input and the default voice to rule out edge cases.
  5. If the problem persists, collect both Dify and ChatTTS/Xinference logs for the failed request to help pinpoint the root cause.

This error is surfaced when the plugin daemon stops streaming audio unexpectedly, so the most likely causes are a crash, misconfiguration, network timeout, or missing/invalid voice setting in the TTS backend. There’s no internal retry or advanced recovery for this in Dify—the fix will be on the plugin or its integration side.

Let me know what you find in the plugin logs or if you need help interpreting them.

Based on the information provided, it's difficult for us to determine what exactly went wrong.

  • Please share the complete DSL.
  • Upgrade to the latest version — we've addressed many tts-related bugs, and you may also want to check for duplicate issues.
  • We haven't received widespread feedback about similar problems.
