IPTV players borrow standard web error codes. Each one points to a specific part of the chain.
| Code | Meaning | Usual fix |
|---|---|---|
| 401 | Not authorised | Check username and password |
| 403 | Forbidden | Account expired, blocked IP, or too many connections |
| 404 | Not found | Channel removed or playlist outdated; refresh the playlist |
| 458 | Connection limit or session issue (player-specific) | Stop other devices, restart the app |
| 500 | Server error | Temporary; wait and retry |
| 502 / 503 | Server busy or unavailable | Temporary; try again shortly |
| 511 | Network authentication required | Hotel or public Wi-Fi login page; open a browser |
401 and 403
Most often login details or account status. A 403 can also appear when your ISP's IP address range is blocked by a server; test on mobile data.
404
The channel or stream ID changed. Refresh the playlist (in TiviMate: Settings, Playlists, Update), or reload the M3U.
503 during a big match
Servers get busy during major events. Give it a minute, then switch to a backup feed of the same channel.
If an error stays after these steps, send Viking IPTV support the code, the channel and the device.
