• Debian 11 is approaching its end-of-life (vendor EOL date - August 31, 2026). Plesk Obsidian 18.0.80 will be the last release to support it.
    If you are running Plesk Obsidian on Debian 11, we recommend you upgrade those servers to Debian 12 using our dist-upgrade tool.
  • We plan to deprecate and remove the support for XML RPC protocol versions earlier than 1.6.9.1 in Plesk Obsidian 18.0.82. We strongly recommend that you update all existing integrations using earlier versions of the XML RPC protocol to comply with the version 1.6.9.1 specification.

FTP Resume

IIS5 and IIS6 support FTP resume by default, however your client should support it too.
 
I am using WS_FTP Pro and it does support FTP resume, however it still doesn't resume the download, is it possible that plesk changes some settings, or registry entries?
 
Hmm, I could not even find how to disable resume in docs from MS. Are you uploading files or downloading? FTP resume will only work for download with IIS.

I have verified that resume is supported on Plesk-controlled server using Unix command-line FTP client:
...
ftp> rest 100
restarting at 100. execute get, put or append to initiate transfer
ftp> get index.html
200 PORT command successful.
350 Restarting at 100.
150 Opening ASCII mode data connection for index.html(557 bytes).
226 Transfer complete.
457 bytes received in 0 seconds (457 bytes/s)
 
Thanks for your input, I figured out that it was my firewall's antivirus feature that would not allow resume.
