Hi @ofh, welcome to the forum - and thanks for using Duplicati!
I suspect the 2.0.3.6 and 2.0.3.7 versions have display bug in them where the progress bar doesn’t always update to the current task so it can appear that it is “stuck”.
Even though the progress bar isn’t updating, do you see progress on the the global Live log with “Profiling” or the “lastPgEvent” on the “System info” page as described here?
