Issue BUG Plesk 18.0.77 - FTP backups no longer work

[jfh]

Since version 18.0.77, FTP backups no longer work, displaying the following error message:

Could not display the list of backups in the FTP Storage: Unable to get ftp dumps list: FTP network error: Transport error: unable to list directory

We have check with the command curl -v --ftp-pasv --ssl -k and everything is fine
