Failed while executing "Backup" with id: 1

I checked my Duplicati tonight and noticed these errors in my log. I have a feeling it has been like this for a while.

Failed while executing "Backup" with id: 1

Could someone point me in a direction?

But this rather looks like… what it says. A (temporary?) http/500, i.e. internal server error on the Backblaze end.

I suspect Tapio is correct that it’s likely a short term issue with Backblaze B2, but one way you could check is to pretend you’re going to do a restore and see what dates are listed in the “Restore from” list as shown here (where I’ve only done a few manual backups):

(By the way, I edited your post by putting “~~~” before and after each error message to make them easier to read.)

How would I check if it is Backblaze causing the issue. I logged in there and didn’t see any errors. I am uploading the screen shot of my restore options. Is there a spot in Duplicati I can see prior contents of uploaded files? Like a file list?
