Unspecified error on backup "one or more errors"

Support
1

I did a bit of homework searching this forum, but it’s tough since the error seems so nonspecific. I have changed nothing but for the past 4 months my backups fail with only “one or more errors occurred” and no specific error flags. Please see most recent log below - appreciate help. I have tried running a database repair, but it makes no difference.

If that means no logs at the usual <job> → Show log, try server’s About → Show log
Unfortunately, the Show button on the error popup only knows about the per-job logs…

Ok thank you. I found this (below) in there. Does it mean anything to you?

suggests your Remote volume size on Options screen 5 isn’t uploading before the default timeout.
Default size is 50 MB, but one can change it (sometimes for good reasons, sometimes by accident).

Choosing sizes in Duplicati

If you like the remote volume size you’re using, try increasing http-operation-timeout to a higher value.
