Below is an example of a video that downloads correctly from YouTube to IIAB, but then when trying to play the video, IIAB button "Watch in Browser - mp4" fails — instead of showing the video at http://192.168.0.108/books/read/1/mp4 — it stalls fo about 1-2 minutes and then shows error "504 Gateway Time-out".
Ryce & Chevy - everyday (live band in a van version 🚙✨)

The failure was confirmed with fresh installs of IIAB Calibre-Web on Ubuntu 24.04 and 25.10
