> [@titou43](#): > > Duplicati.Library.Modules.Builtin.ReportHelper-ReportSubmitError That error is from the reporting module (http reporting, email reporting, jabber reporting, or telegram reporting). However, the error message is not exact enough for me to figure out what is causing it. Can you try to use the UI, then click “About”, “Show log” (the button at the top, to the right): ![Screenshot 2025-05-26 at 11.49.40](https://forum.duplicati.com/uploads/default/original/2X/e/e72d761a4246f86f789bc75a912eaa85768e6812.png) This should show the same error message, but if you click it, it will expand and show some context. If you can copy-and-paste the entire message, then I can perhaps diagnose it a bit further. ---
