Applicable to:

  • Plesk for Linux

Note: This article has the reference to the issue with the fix available:

  • #PPPM-6502 "Trying to configure FTP storage resulted in an error if the FTP server did not allow to resume uploads and downloads, or to upload the .ftpaccess file."
    Fixed in:
Please consider updating your server:

Symptoms

When trying to save FTP Storage Settings in the Backup Manager, the following error appears:

ERR [panel] Curl error: Unable to resume an interrupted upload: (25) Upload failed (at start/before it took off): Last FTP request: STOR .ftpaccess: Last FTP response: 550 .ftpaccess: Forbidden filename: Connection to the FTP server has lost

And the settings are not saved.

Cause

This is a known issue #PPPM-6502 . The FTP server has PathDenyFilter option for .ftpaccess enabled. Such option specifies a regular expression which must not match any uploaded pathnames. If the regex does match, a Forbidden filename error is returned to the client.

Workaround

Disable the PathDenyFilter on the FTP server or use another FTP server.
