#4431 Auth Deppl secret required

This error occurs because you selected DeepL as the translation channel but did not provide an API key (Auth Key). DeepL requires authentication to use its translation service.

How to fix:

1. Obtain a DeepL API key from deepl.com/pro-api.
2. In pyVideoTrans, go to Menu → Translation Settings → DeepL Settings.
3. Paste your key into the DeepL Auth Key field.
4. If you are using the free DeepLX self-hosted service, ensure it is correctly deployed and enter its address in Menu → Translation Settings → DeepLX API Address.

If you do not wish to use DeepL, simply switch to another translation channel (e.g., Google, Microsoft, or an AI model like DeepSeek).
