The root cause of this error is that Microsoft has changed the authentication logic of its free Edge-TTS interface, so the old v3.97 you are using no longer works and the WebSocket handshake is rejected with 403 Invalid response status (the no running event loop line is only an internal exception caught and re-raised, not the real cause). It is also possible that a network proxy is interfering.

Step 1: Upgrade the software (mandatory, the 403 is fixed in v4.16 and later)

  • Portable (packaged) build: download the latest full package from https://pyvideotrans.com/downpackage and overwrite the whole software directory; copying only sp.exe is not enough.
  • Source deployment: run uv add git+https://github.com/rany2/edge-tts.git; if that fails, run uv remove edge-tts first and then run the add command again.

Step 2: Rule out proxy interference

  • Clear the proxy box on the main interface; leave it empty if you do not need a proxy.
  • Create an empty edgetts-noproxy.txt file in the software root directory to force Edge-TTS to bypass the proxy.

Step 3: Avoid rate limiting (403 is sometimes also caused by too many requests)

  • Go to Menu → Tools/Options → Advanced Options → Dubbing Settings, set EdgeTTS Max Concurrency to 1, and set Post-Dubbing Delay (s) to 5~10.

Step 4: If it still fails after the above steps

  • Switch to another free TTS channel such as gTTS, or to a built-in channel such as Qwen3-TTS(Built-in) for dubbing.

If it still fails after upgrading, please provide the latest error log from the logs/ folder in the software installation directory.
