• 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.

Do you know how to solve the problem?

Thanks
 
The cause is probably a corrupted /opt/psa/admin/conf/httpsd.pem file. Plesk create automatic backups of that file, so you should be able to restore it from such a backup:

ls -l /opt/psa/admin/conf/httpsd.pem*
should result in something like
-r-------- 1 root root 1922 Jan 27 12:59 /opt/psa/admin/conf/httpsd.pem
-r-------- 1 root root 6525 Jan 27 12:55 /opt/psa/admin/conf/httpsd.pem.sav

Then you can
mv /opt/psa/admin/conf/httpsd.pem /opt/psa/admin/conf/httpsd.pem_not_working
cp -p /opt/psa/admin/conf/httpsd.pem.sav /opt/psa/admin/conf/httpsd.pem

Afterwards, login to Plesk an create a new certificate as described in https://support.plesk.com/hc/en-us/articles/12377713798039 .
