Operation timed out Failed to upload the chunk

Hi!
I’m getting this operations timeout since I upgraded to Big Sur. I don’t know if it’s related or not. The last time I got this error I did a check + prune and it finished uploading.
This backup is around 230gb of data, but I don’t know where it is right now. I have started it multiple times after getting this error and it keeps going for an hour or so before getting the error again.

What should I do?

Running backup command from /Users/carlosferrarifotografia/.duplicacy-web/repositories/localhost/0 to back up /Volumes/CF1 DADOS

Options: [-log backup -storage CFF_BACKUP-NAS -threads 4 -stats]

Can this caused by a temporary network error (assuming /Volumes/CFF BACKUP is a network mounted drive)?

Sorry for the late reply.

It seems related to my NAS and Big Sur. I couldn’t figure this out yet. I might test different connection types, currently I’m connecting with SMB3. Gonna enable AFP and for SMB2 to see if it solves.

Gonna search for SMB3 problems with Big Sur as well.

For now, if it fails, I run it again and again until it finishes…
