• 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.

New Pleskian
I just can't get Plesk to work. I keep getting this error:
Couldn't insert domain in Plesk. Plesk returned: Protocol version '1.6.0.1' is not supported. Current protocol version is '1.6.9.1'.

Is it Plesk or ClientExec that I need to fix, and how?
Thank you
 
From the looks of the error I would say it's an issue with ClientExec. I would suggest to contact their support for assistents.

The latest Plesk Obsidian version (currently 18.0.41) fully support protocol version '1.6.9.1'. Protocol version 1.6.0.1 belongs to a way older Plesk version.
 
For anyone experiencing this same error and unable to find a solution, I'm posting the solution.
Somehow, the 'Plesk10' plugin was missing from my ClientExec install. If you have this issue you can get it from GitHub or the ClientExec people can help.
You must use Plesk10, not Plesk, as the plugin for your server
