Python Code Fix for YouTube App

I have a small Python app running locally that displays videos from a specific YouTube channel, allowing me to download them and then upload to my own channel. However, after setting it up on cPanel, it encounters a cookie error during the downloading process, despite my attempts to rectify this by exporting cookies from Chrome and adjusting the code accordingly.

I need an experienced Python developer with expertise in YouTube API and 'youtube-dl' library to debug and fix my app.

Key Requirements:
- Fix the video downloading issue
- Inspect and correct the code for cPanel compatibility
- Ensure the entire process (displaying, downloading, uploading) works seamlessly

Please check the attached error log file for more details.

Your quote should include:
- The phrase: 'Log checked'
- Your proposed solution

I will only consider quotes that include this phrase.
