## "Login failed" or "authorisation failed"

1. Re-enter the username and password by copying and pasting; they are case-sensitive.
2. Check the server address includes "http://" or "https://" and the port, exactly as sent.
3. Make sure your subscription has not expired.
4. Stop playback on other devices: if every screen on your plan is in use, new logins are refused.
5. Check the device’s **date and time** are correct: a wrong clock can break secure connections.

## "Playback error" or a black screen

- Try another channel. If others play, that one stream may be temporarily offline.
- Switch the player or decoder option in the app’s settings.
- If you are on 4K with an older device, try an HD channel: the device may not decode HEVC.
- Clear the app cache, then restart the device from the mains.

## The app keeps stopping or will not open

Messages such as "Unfortunately IPTV Smarters has stopped" mean the app crashed. Clear its cache and data under **Settings → Applications**, restart the device and update or reinstall the app from its official source. If you installed a modified version from an unofficial site, remove it: those builds are unstable and can be unsafe. See [IPTV Smarters setup](https://streampulsetv.co.uk/iptv-setup/iptv-smarters/).

## Not working on a Firestick

- Restart the stick from the mains and check for Fire TV software updates.
- Turn off **Data Monitoring** under Settings → Preferences.
- Check the app is still installed and allowed to run; some updates reset permissions.
- If you replaced an older stick, note that some newer Fire TV models run Vega OS and only install Appstore apps. See our [Fire TV guide](https://streampulsetv.co.uk/iptv-devices/firestick/).

## Channels or films missing

Refresh the playlist in the app (often "Update channels" or "Reload playlist") and check whether you have hidden a channel group. Line-ups on licensed services change when rights agreements change, so a channel can be withdrawn. Ask us if you are unsure.

## Your broadband provider and blocking

UK broadband providers are ordered by the courts to block servers used by unlicensed streaming services. A licensed service should not be affected. If an app only fails on one broadband connection, mention it when you contact us. Background: [why ISPs block some IPTV services](https://streampulsetv.co.uk/iptv-legal/isp-blocking/).

## Frequently asked questions

**Why is my IPTV not loading?**

Check your login details, your subscription’s expiry date and your connection, then restart the device and app. If nothing loads on any device, see [is IPTV down?](https://streampulsetv.co.uk/iptv-troubleshooting/iptv-down/).

**Why is IPTV Smarters not working?**

Common causes are an expired login, a mistyped server address, too many screens in use or an outdated app. Clear its cache, update it and re-enter your details.

**IPTV works on my phone but not my TV. Why?**

The TV device or its connection is the problem: restart it, clear the app cache, check its date and time, and try Ethernet.
