• 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 hostname result not secured

Try to secure your Plesk with simple SSLIt! extension:

 
Listen, we won’t come to anything. Just to say, I did this according to this link and nothing works for me, at least not constructively. It is impossible to understand the reason, only that something doesn't work.
 
well, what information can I give to arrive at a solution? Any kind of log? My problem is that for some days the SSL certificate for the plesk administration area has not been valid. If I could give you more detailed information I would have given it ... unfortunately I don't know how to investigate further
 
I'd suggest you contact Plesk Support Team. They will check the issue directly on your server and found the reason. Looks like forum discussions are not effective in your case.
