Before you write about a failed download
Most failures have a known cause and a fix that takes a moment — silent files, missing resolutions, private videos, rate limits and expired links are all covered on Fixes & FAQ. If your problem is not there, send the link you pasted, the quality you chose, and roughly when you tried; that is usually enough for us to find the request in our logs.
