Hello,
I am testing before bying CloudBerry Backup running on a Unraid server (docker).
I am able to connect to my Backblaze account (app key ID, bucket name etc.)
When running my backup I have this error message:
an error occured code 1003

Same error if I am backuping a big or small size file.

still preparing for starting ...
Syncro stop after 5s .... with error

Ideas ?
Thx
