Resolved Backup error via FTP

[Jeffrey van Oostenbrugge]

Hi,

We're using Plesk Obisidian with CentOS7.
We've used Plesk Onyx before and made backups to an external storage, this works for us.

But the moment we started using Plesk Obisidian and did the exact same thing, we started to get error messages.
This is the message we get:
Unable to upload the archive clients/shop51752/domains/sprookjeshoek.nl/backup_user-data_1911121142.tgz to the external storage: Cannot read public key

I tried using a password instead of the Plesk encryption key, but it still gives the same error message.

I'm not really sure how to fix this issue.

Regenerate the backup sign key using below command:

/usr/local/psa/admin/sbin/backup_sign --generate

Thanks m3lezZ, it worked!
