| Error Message | Cause | Fix |
|---|---|---|
| Failed to connect to server | DNS blocking by ISP, incorrect server URL, firewall, or server downtime | Change DNS to 1.1.1.1 or 8.8.8.8. Verify server URL. Test portal in browser. Restart router. |
| Checksum error | Network data corruption during stream delivery | Switch to Ethernet. Restart router. Clear app cache and re-add playlist. |

| No data / received | Server not sending stream data, or connection dropped mid-stream | Restart app and router. Try a different channel. Check internet speed and stability. |
| Stream not found | Channel temporarily offline, stream URL changed, or server issue with specific stream | Refresh channel list. Try another channel. Restart app. Contact provider if persistent. |

Error Troubleshooting Steps
- Identify the exact error message. Write it down or take a screenshot. The specific wording tells you whether the problem is network-related, credentials-related, or a server issue.
- Check your internet connection. Open a website in a browser. Run a speed test. If your internet is down or slow, fix that first — many IPTV errors are just symptoms of a bad connection.
- Verify subscription and credentials. Log into your provider dashboard. If your subscription is active, re-enter your credentials exactly as provided — copy-paste from the welcome email.
- Clear app cache and data. On your device settings, clear the IPTV app's cache first. If the error persists, clear the app data (this will require re-entering credentials). See buffering fixes for detailed instructions.
- Try a different IPTV player. Switch between TiviMate, IPTV Smarters, and VLC. If the error only appears in one app, the problem is app-specific. See connection problems for more player troubleshooting.
- Contact support with the error details. If the error persists across multiple apps and networks, provide your provider with: the exact error message, your username, device type, and when the error started.
Error Codes FAQs
This error means your IPTV app cannot reach the provider's server. It's usually caused by DNS blocking, an incorrect server URL, a firewall, or the server being temporarily down. Try changing your DNS to 1.1.1.1 or 8.8.8.8, verify the server URL, and test if the portal page loads in a browser.
A checksum error means the data your device received doesn't match what was sent — usually due to network corruption during transmission. It's caused by unstable internet connections, Wi-Fi interference, or ISP throttling. Fix it by switching to Ethernet, restarting your router, or clearing the app cache and re-adding the playlist.
This error means the server rejected your login credentials. Double-check your username, password, and server URL are copied exactly from your provider's welcome email — including case, special characters, and without extra spaces. If credentials are correct, your subscription may have expired. Check your account status with your provider.
These errors mean the specific channel or stream isn't available. Causes include: the channel is temporarily offline, the stream URL has changed, or the server is experiencing issues with that particular stream. Try refreshing the channel list, switching to a different channel, or restarting the app. If it persists, contact your provider.
