Frequently asked questions

Why does IPTV say login failed?

Most login failures are caused by a wrong server URL, username, password, expired trial, or extra spaces when copying.

Why are channels missing?

The playlist may not have fully synced, or the app may need a refresh or restart.

Why do I get black screen?

Try another channel, restart the app, or change decoder settings if your player offers them.

When should I contact support?

Contact support after basic checks, especially if all categories fail or the login appears inactive.
