Unable to complete backup using Backblaze B2 storage

Hello,
In one specific computer, the backup never ends.
The backup always stuck in “Verifying backend data” or “Waiting for upload”
I tried to rebuild database and it stuck in "Backend event: List Started: ()

Hello and welcome. If you look at the bucket in the B2 web console, do you see any Duplicati files at all?

If at least one backup didn’t succeed, you won’t have any dlist files (filelists) so recreate will fail with “No filelists found on the remote destination.”

The problem was solved by itself.
I don’t understand what happened.
Thank you for reply.
