• 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.

Issue Plesk goes ERR_CONNECTION_REFUSED everytime I make changes on my website.

In Plesk
- go to the subscription
- Open Web Application Firewall
- Click on the link "Error Log File"

Search for entries like: [id "33340162"]
If the entry the logfile matches the date/time when you got locked out, copy the number and go back to Web Application Firewall
- Paste number in "Security rule IDs"
- Click [OK] to save the settings.
This will disable that firewall rule.

Repeat this for other IDs if the problem still persists
