DominoPDF connects to the Domino server via HTTP / HTTPS and requests the HTML response from a specified URL. If the Domino HTTP task is not operating correctly or the URL cannot be resolved DominoPDF may still create PDF output as the request did not error. If the HTTP request encounters an error the PDF will not be created. If the Domino server returns a 401, 500 etc. error the PDF will still be created with the appropriate error message in the content so the cause can be investigated.
