Resolved Error when deleting SSL certificate

[Cordal]

On a server with plesk 12.5.30 #70, running under debian 8, the default certificate that installs plesk expired, I generated a new certificate and assigned it to protect plesk plesk, and I want to delete the expired certificate but I get the following error::
"SSL certificates could not be removed.
One or more certificates are assigned to the IP addresses/domains."

And since none of the server's ips use that certificate, however, it tells me that they still use 4 ip/domains.

How can I find out who is using that certificate?

I think this problem is addressed in the following KB - Unable to remove certificate: One or several certificates are assigned to the IP addresses or domains. Does this solve your issue?
