What does “YouTube Error Code 4” mean and how can I fix it?

I keep getting “Error Code 4” on YouTube, and videos won’t load or play. Does anyone know what causes this or any reliable fix?

YouTube Error Code 4 usually means a network or cache issue preventing videos from loading. To fix it, refresh the page, clear browser cache, or restart the app. Disable VPNs, proxies, or ad-blockers, and check your internet connection. Updating your browser or the YouTube app often resolves the problem.
