Getting a '401 Authorisation Required' Error – How Do I Fix This? or Why Am I Seeing '401 Authorisati

401 authorisation required usually means “nope, not letting you in.”

Things to try:
- If it’s Basic Auth, make sure you’re not URL-encoding the creds twice.
- For tokens, check the expiry. JWT.io can help decode them.
- Maybe the server expects a different auth method entirely (like OAuth2 instead of API key).

Fiddler or Chrome DevTools can help sniff the requests.
