This is the single most useful question you can ask before changing anything. Try two or three other channels in different categories before you assume the whole service is down. If only one stalls, the fault sits with that channel's source, not your setup, and no local fix reaches it. If a whole category buffers together, like every channel in one group, it likely shares one upstream server feed, and again nothing on your device changes that. If literally everything buffers, live and on-demand alike, the cause is your line, the app's session, or a device setting, and that's the one case where local fixes actually help. Skipping this step is why so many people restart a router that was never the problem.

1. 1One channel = source problem
2. 2One group = server-side fault
3. 3Everything = line, player, or session

Leave the stalled channel, wait a few seconds, then switch back to it. If playback comes back clean, the session itself stalled, and your bandwidth was never the cause of what you just saw. This test takes under ten seconds and rules out half the wrong fixes people try, like restarting the router or calling their internet provider, when nothing was actually wrong with the connection. A stuck session can happen for reasons that have nothing to do with speed, so a fresh session on the same line often just works. Almost no ranking page for this query names this test, even though it costs nothing and is the cheapest diagnostic available to you before touching a single setting.

Setting the buffer to none or minimum means the app starts playback sooner and catches up faster after any stall, instead of building a growing backlog behind a large buffer window that keeps you further and further behind live. Switching to a public DNS resolver usually cuts the lookup delay compared with your ISP's default resolver, and that delay can look identical to buffering on screen even though it happens before a single video segment has actually loaded. Both changes take under a minute to make, and both target a specific, checkable mechanism rather than being a vague catch-all fix you try because nothing else worked.

Some buffering comes from oversold server capacity on the provider's side, and no device setting reaches that layer no matter how carefully you tune it. If you've scoped the issue, run the switch test, and checked your buffer and DNS settings, and it's still happening across more than one device and more than one network, that's a real sign the cause has moved past anything local. That's a reason to look at the provider's own uptime figure instead of tweaking your setup further, since a specific number like 99.99 percent, about 53 minutes of downtime a year, tells you honestly how often this should happen at all.
