• 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 Let's Encrypt issue with TLS-SNI-01

@Kirill Nikolaev

I am pretty sure it is not of importance: the Let's Encrypt Plesk extension uses the webroot approach, which is a different way of checking the challenge.

Moreover, Let's Encrypt closed the method of the TLS-SNI-01 challenge.

Plesk LE extension doesn't use `TLS-SNI-01 challenge type`, therefore Plesk LE extension is not affected.
We use webroot `http-01`.
