• 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.

Resolved IP Address Banning (Fail2Ban)

The fact that there is no option to enable jails is that Fail2Ban is currently switched off in Plesk.

To enable Fail2Ban and jails perform the following steps:

  1. In Plesk go to Tools & Settings > IP Address Banning (Fail2Ban) > Settings tab and click Enable intrusion detection .

  2. Click OK to apply the changes.

  3. Switch to the Jails tab, select required jails and click Switch On .
