This is using the 4K Video Downloader.
Every now and then when I’m downloading a bunch of videos from YouTube, one of them will not finish downloading. No error messages, it just keeps going but never finishes. It would be nice to have some kind of restart option. If I place my mouse over a stalled download, it has a pause button, which doesn’t work.
You can right-click on a stalled download and Copy Link Address again. Then click on Paste Link. That will start a second download of the video.
You can Open the Link in Browser, which sends you back to the YouTube page for that video. You can start the download process again from there.
Or you can Restart the 4K downloader. When I restart 4K I immediately get a message saying, Some downloads were interrupted last time. Do you want to re-download them? I click on the Download button. Boom. They’re done.
