The error indicates a proxy authentication issue when connecting to Google Translate. This occurs because your system is behind a proxy that requires authentication, but pyVideoTrans cannot automatically use your system's proxy settings.

Solution:

  1. Disable system proxy temporarily while using pyVideoTrans, or

  2. Configure proxy in pyVideoTrans settings:

    • Go to Translation Settings in the menu
    • Set up your proxy with authentication in the network settings
    • Make sure to include your proxy username and password if required

Alternative workaround:

  • Switch to a different translation service that doesn't require proxy authentication, such as:

    • Microsoft Translator
    • DeepL
    • OpenAI/Gemini/DeepSeek (if you have API keys)
    • Local translation models

Since you're using Google Translate (gTTS) which is having proxy connection issues, changing to another translation provider should resolve this immediately without needing to configure proxy settings.

The error occurs during the TTS (text-to-speech) phase when trying to connect to Google's servers. Using an alternative translation service will bypass this proxy authentication requirement entirely.
