invalid_client

OAuth (Sign in with Tickwire): the client could not be identified or authenticated.

HTTP 400, 401.

Likely causes:

• Unknown client_id: register the app first (DCR) or use a valid client metadata document URL.
• Wrong or missing client secret for a confidential client, or a secret sent by a public client.
• The client metadata document could not be loaded or is invalid.
• The app sent a token exchange request with credentials we do not accept.

What to do: Check the client registration and its credentials; re-register if needed.

Retry: No. The same request gets the same answer; change something first.
