Large upload stuck at "waiting for upload to finish"

I have a ~1TB backup (500MB increments) going to an iDrive cloud account. It’s been uploading for weeks and just finished however it’s stuck on “waiting for upload to finish”. The last remote log message was:

  • Nov 3, 2020 1:48 AM: put

And the last entry from the verbose live log:

Nov 3, 2020 1:48 AM: Backend event: Put - Completed: (921.21 KB)

And it’s been stuck since. I’m on macos 10.14.6 with duplicati

I’ve read some of the similar topics on the forum and none seem to apply in this case. Help appreciated! Thanks!
