A structured way to identify and fix the server rejects authentication without changing random settings or exposing private credentials.
Fix the server rejects authentication with a structured UK troubleshooting process covering credentials, apps, devices, Wi-Fi, broadband and source-side faults.
HTTP 401 normally indicates that valid authentication was not supplied or the account is no longer accepted.
A single character or space can fail authentication.
Credentials may be valid on another portal or port.
The subscription may need renewal or reactivation.
The player may be reusing outdated credentials.
Close and reopen the player, then restart the device if necessary.
Use a compatible second player to isolate app-specific settings.
Test the same authorised account without changing the home network.
| Test | Result | What it suggests |
|---|---|---|
| Works in a second player | First player fails | Application configuration or decoder is likely involved |
| Works on a second device | First device fails | Hardware, storage, OS or local app issue |
| Works on another connection | Home broadband fails | Wi-Fi, router, DNS or ISP path is involved |
| Fails everywhere | All comparisons fail | Account, source or provider-side issue is more likely |
