Find which request failed
A player can display a channel list using saved information while its next video request fails authentication. That makes “the menu works” useful evidence, but not proof that video access is currently authorized. Note whether the error appears when signing in, opening the list, starting a programme or seeking through a recording.
If a diagnostic panel names a resource, record only its hostname and general role. Remove usernames, passwords, query values and signed tokens. A complete media address can be a working credential even when it does not look like a password.
Make one careful credential check
Compare the server address and username with the current instructions obtained through the account's established contact route. Check for a space pasted before or after a field and for a password manager filling an old entry. Keep the original entry until the comparison is complete; changing several fields at once destroys the useful baseline.
Re-enter the approved details once, then make one ordinary playback attempt. If authentication succeeds, repeat the same programme before trying anything else. If the same challenge returns, stop cycling passwords. An account-side access check is more useful than another router restart.
A challenge is different from a refusal
A genuine 401 normally includes an authentication challenge in the response headers. A 403 means the server refuses the request; sending the same credentials again need not help. Players sometimes replace both with a general login message, so quote the visible wording and distinguish it from a code captured in a diagnostic log.
For example, “list refresh succeeds; first segment receives 401 at 20:14” identifies a different boundary from “sign-in form receives 401 immediately.” These are illustrative reports, not observations of this service. They help support choose between checking the account entry point and the media access path.
Keep the recovery proportional
A 401 is not a reason to disable TLS, install a certificate, open incoming router ports or share a playlist publicly. Those actions do not establish the missing permission. Preserve favourites and settings while the account is checked; a reinstall can erase useful evidence without changing authorization.
Ask the account operator to confirm which access details and endpoint are current. A helpful report includes the time and time zone, player version, failing stage and whether another permitted programme works. Send secret material only through an explicitly appropriate private process, never in a public screenshot or a search query.

Does 401 prove my payment failed?
No. It reports authentication for a particular request. Payment status and current access must be checked against the account record.
