summary	The “401 Authorization Required” error message with Nginx indicates that the request being made lacks the necessary authentication credentials. This typically means the server isn’t recognizing the user’s identity or doesn't have permission to access the requested resource. Common causes include: * Missing or Incorrect Authentication Header: The client isn't sending an `Authorization` header with a valid bearer token, API key, or other authentication information. * Expired Token: The authentication token used in the header has expired. * Incorrect Token Format: The token provided in the header isn’t in the format expected by the server. * Incorrect Nginx Configuration: Nginx is not configured to properly handle authentication requests, or the authentication configuration itself is flawed. * Firewall Issues: A firewall might be blocking the authentication header. To resolve this, you’ll need to verify the authentication credentials being sent, ensure they are correctly formatted, and check the Nginx configuration to confirm it’s properly set up for authentication.
