YouTube keeps pausing mainly due to a few common reasons: a poor or unstable internet connection causing buffering delays, YouTube's "Remind Me to Take a Break" feature which automatically pauses videos, intermittent disconnection of headphones, conflicting browser extensions (such as ad blockers), overloaded cache and cookies, or background apps interfering with playback. Other contributing factors include outdated YouTube app versions, battery saver modes, device storage being full, hardware or software glitches, and interruptions from ads. Troubleshooting usually involves checking and improving internet connectivity, disabling the "Remind Me to Take a Break" feature, clearing cache and cookies, disabling problematic browser extensions, updating the app, and ensuring no hardware or accessory issues are present.
