Many IPTV players show raw server responses — numbers like 401 or 403 — instead of friendly messages. They're actually useful: each code tells you roughly where the problem is.
Exact wording varies between apps, so use this as a guide. It's part of our IPTV troubleshooting guide.
Quick answer
Common IPTV errors: 401 means the login was rejected, 403 means access was refused (often an expired account or connection limit), 404 means the channel or playlist wasn't found, 502/503 are temporary server errors, and "max connections reached" means all your simultaneous streams are in use.
Common IPTV errors at a glance
| Error | What it usually means | What to do |
|---|---|---|
| 401 Unauthorized / Authorization failed | Wrong username, password or server | Re-enter login exactly; check capitals and spaces |
| 403 Forbidden | Access refused — e.g. expired account or connection limit | Check account status; close other streams |
| 404 Not Found | The channel or playlist path doesn't exist | Refresh the playlist; check the URL is complete |
| Max connections reached | All your simultaneous streams are in use | Stop playback on another device |
| Account expired | Subscription period has ended | Renew, then restart the player |
| 502 / 503 / 504 | Server temporarily unavailable or overloaded | Wait a few minutes and retry |
| Unable to connect / timeout | Network or DNS problem | Check internet; try another DNS |
| Invalid playlist / parse error | The M3U didn't download correctly | Re-add the URL; try Xtream Codes login |
Login errors in detail
Most login errors are typos. Server URLs must include http:// or https:// and the port number exactly as provided. Usernames and passwords are case-sensitive, and phone keyboards like to add capital letters or trailing spaces. Our add M3U playlist guide shows the correct format.
"Max connections reached"
This means your plan's simultaneous streams are all in use. Common culprits: a player still running in the background on another device, a TV left on another input with the stream playing, or shared login details. Close players fully, and if you regularly need more, see 1 device or 2?.
Server and network errors
5xx errors are usually temporary. If they persist across devices for more than a few minutes, contact support. Timeouts that happen only on one device point to its network — check the home network guide.
Player-specific errors
Messages like "source error" or "playback failed" come from the player rather than the server. They usually mean the player couldn't decode the stream: switch format and decoder, or try another player. See channels not loading.
IPTV error codes: frequently asked questions
The server rejected your login. Re-enter the server URL, username and password exactly as provided.
Access was refused — often because the account has expired, the connection limit is reached, or access is restricted. Check your account and close other streams.
Stop playback on other devices and close players running in the background. Upgrade to more connections if you regularly need them.
Conclusion
Error codes point to where the problem is: login, account, playlist or server. Fix the matching layer rather than changing everything at once.
