Feature request View logs for direct restore from backup files gives a way to get a log file to get a look at those 841 errors on the web UI. Somewhat easier than a log file for one-time use is to look at live log by opening another browser tab to Duplicati’s About --> Show log --> Live --> Error while trying direct restore. There’s no need to show the whole thing if it gets repetitive, but some idea of the sort of errors is needed.
