Issue Backup to FTPS server fails after upgrade to Plesk 18.0.64

18.0.64

Hi all!

One of our servers automatically upgraded to Plesk 18.0.64. Since the upgrade the daily backup job to an FTPS server fails with the following error message:

Unable to create the remote backup: Curl error: Unable to finish an upload: (28) Timeout was reached: Last FTP request: APPE backup_2409280008_2410030008.tar: Last FTP response: 125 Data connection already open; Transfer starting: Connection to the FTP server has lost

When we disable FTPS in the remote repository settings, the job runs without problems.

When we try to reenable FTPS in the remote repository settings, the following error message is displayed (I have redacted the hostname of the backup server as well as the username):

Fehler: Datei kann nicht in den Speicher hochgeladen werden: Stream error: /check0/test: Curl error: Unable to finish an upload: (28) Timeout was reached: Last FTP request: APPE test: Last FTP response: 125 Data connection already open; Transfer starting: Connection to the FTP server has lost Überprüfen Sie, ob Sie Berechtigungen zum Hochladen von Dateien im Speicher haben. Sie können dies unabhängig mit den folgenden Befehlen überprüfen: echo 123

When I manually run this command from the affected server, curl successfully connects to the backup repository and creates the directory as well as the test-file.txt.

Does anyone else see this error? Does anyone have any suggestions on how to fix this?

Thanks in advance!

The command got truncated unfortunately:

echo 123 | curl -T - --ftp-create-dirs -v --ftp-pasv --ssl -k -u ftpusername 'ftp://backup.example.com/./test-dir/test-file.txt' curl -v --ftp-pasv --ssl -k -u ftpusername 'ftp://backup.example.com/./test-dir/'
