• 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.

What are the ports that need to be open to run plesk on a server using a firewall.
 
We have open from the Internet trough a firewall to the Webserver the following ports:

TCP Ports:
21 ftp
25 smtp
53 DNS
80 http
110 pop3
443 https ( for user Sites)
8443 https (for Plesk Admin)

UDP Ports:

53 DNS


that should be enough from the internet to the webserver for working. of course the traffic back needs also to get trough. but if you chause a staitfull firewall this will be working by default.
 
One more if you want Terminal Services access.

Port 3389
