A crash on launch, before you ever reach a channel, usually means the local cache is damaged. This happens most often right after an update, when a background write to the app's channel database gets interrupted partway through. The app opens, tries to read a database that is half-written, and closes itself instead of showing an error. Restarting the app rarely fixes this because the same broken file loads again on the next launch. Clearing the app's cache and data forces it to rebuild that file from your playlist the next time it opens, which resolves this specific cause. If the crash still happens after a clean cache, the fault has moved from the app to the playlist source itself, and the next section covers that.

1. 1Clear cache and data, not just force-close
2. 2Reload the playlist fresh rather than retrying the cached one

When every channel shows the same empty error, the app opened fine but has nothing valid to pull from. That points to the playlist URL or Xtream login, not the app itself. Providers occasionally rotate a session token or reissue a line, and the app keeps trying the old one until you replace it. Re-entering a fresh playlist URL or login from your account panel clears this in most cases. If a brand-new playlist still returns nothing, that is the moment to treat it as a provider-side outage rather than a local setting, since no amount of restarting fixes a credential that has actually changed on the server end.

A live channel does not arrive as one continuous file. It comes in as a series of short segments, each covering roughly six seconds of video. Your player downloads segments slightly ahead of what is on screen and holds them in a buffer. If your connection drops a segment and cannot recover it before the buffer runs dry, the picture freezes visibly, and a large buffer setting can make this worse by holding onto a stalled segment instead of skipping it. Setting the buffer to none tells the player to drop a bad segment immediately and move on, which clears up freezing that follows you across every channel. Switching to a public DNS resolver also speeds up how fast each segment request resolves.

A post-update regression is a distinct, recurring cause, separate from a broken cache or an expired login. Updates sometimes reset saved playback settings, most commonly the buffer value, or invalidate a stored login token even though your subscription is untouched. This reads exactly like an account problem because the symptom looks identical, but the fix is different: re-save your playlist login and reset your buffer preference after any update, rather than assuming your line stopped working. If the same break repeats after every update, mention that pattern specifically when you contact support.
