What it means

What happened

pastebin.ca does not recognize the app (client) that started this authorization request.

Why

Why it might have happened

  • The app was never registered with pastebin.ca, or its registration was removed.
  • The app may be misconfigured and sending the wrong client identifier.
  • A stale or copied connection link may reference an app that no longer exists.
Next steps

What you can try

  1. Start the connection again from the app so it can register or re-register itself.
  2. If you are the app developer, confirm the client_id and redirect URL match a current registration.
  3. Contact the app developer with this error code if it keeps happening.
