    Seems a similar Bug has be reintroduced in current latest release Plesk Obsidian Version 18.0.53
    Sad fact: In this "issue" of the bug the workaround mentioned by editing the panel.ini does not work anymore :-/
    Please fix - by now no backup is possible on any updated instances (other servers that are still on 18.0.53 Update 3 don't face that problem).

    It seems like this error is back. 

    Since Plesk Obsidian 18.0.68 Update 2 has been installed (April 8th, 2025), we get this error for every single backup, on two different hosts. 

    Plesk entry point: https://******:8443/

    The following errors occurred during the scheduled backup process:

    Transport error: unable to read file /check4/test: Curl error: Unable to resume an interrupted download: (28) Timeout was reached: The last FTP request: PASS *****: The last FTP response: 421 I can't accept more than 3 connections as the same user: Connection to the FTP server has lost
