Summary

The request lacks valid authentication credentials. The server cannot identify who is making the request.

When it occurs

• No client certificate or API token was provided.
• The provided certificate has expired or been revoked.
• The authentication token is invalid or malformed.
• The session has expired and reauthentication is required.

How to fix

• Ensure you are sending a valid client certificate or API key with the request.
• Check that the certificate is within its validity period and has not been revoked.
• Re-authenticate and obtain a fresh token if the session has expired.
• Verify that the correct certificate or credential is configured in your HTTP client.
