• 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.

Will restricting Plesk port 8443 with hardware firewall cause issues?

Hey there, we have a hardware firewall and would like to restrict Plesk port 8443 to only certain IPs. Will this affect any Plesk services?

Of course, we could use the inbuilt Plesk 11 feature "Restrict Administrative Access" but I'd prefer to do it at the hardware level if it doesn't cause any issues.
 
:8443 is a control panel of Plesk. As long as your list of allowed IPs includes every user and service (i.e. billing) using or integrating Plesk - you should be fine.
