Applicable to:
- Plesk for Linux
- Plesk for Windows
Symptoms
Plesk Backup Manager loads very slowly and opens with one of the the following warning messages:
PLESK_WARN: Warning: Could not display the list of backups in the FTP Storage: Unable to connect to the remote server. Please check the FTP storage settings.
PLESK_WARN: Warning: Unable to access the storage: Transport error: unable to list directory: Curl error: (7) Couldn't connect to server: Last FTP request: Last FTP response:
Make sure you have entered the correct storage settings. You can check them independently with the command:
curl -v --ftp-pasv --ssl -k -u ftpuser 'ftp://server.example.com//backups/'
Cause
The remote FTP server is unreachable from the Plesk server.
Resolution
-
Check if the remote FTP server is up and running.
-
Check if the remote FTP server is available for FTP connections from the Plesk server. Run this command from your Plesk server:
# curl -v --ftp-pasv --ssl -k -u <ftp_server_address>
Additional Information
Additionally, it is possible to reduce FTP server timeout so that Plesk Backup Manager will take less time to open when an FTP server is not reachable:
-
Connect to the Plesk server via SSH.
-
Add the following lines to the Plesk configuration file
/usr/local/psa/admin/conf/panel.ini:Note: All values are in seconds.
CONFIG_TEXT: [pmm]
ftpResponseTimeout = 30
ftpConnectionTimeout = 150
ftpRequestTimeout = 150

This doesn't solve the problem.
I too have this same issue with no resolution from the suggested fix.
My remote ftp backup server is down, and access to the backup manager takes 3 or 4 minutes.
I changed the ini as above, and rebooted.
Plesk 18.0.46 last update Sept 19
Hi @Tippy
If your remote FTP server continues to be down, I'd recommend to temporary disable this FTP server in Plesk at Tools & Settings > Backup Manager > Remote Storage Settings > FTP(S) > Use FTP(S) storage.
Otherwise, make sure the remote FTP server is accessible from your Plesk server.
By the way, reboot is not required after you make changes in /usr/local/psa/admin/conf/panel.ini.
