Issue SSL certificate to secure Plesk IP address issue (Not Lets Encrypt)

[Matt63]

Server operating system version

Ubuntu 22.04.4 LTS

Plesk version and microupdate number

Plesk Obsidian 18.0.60 Update #1,

Hi there,

I need to secure the public IP address for the Plesk portal (requested by a client). I have purchased a specialist SSL certificate that can be used to secure IP addresses. The site I have running on the hosting has its own Lets Encrypt certificate on it.

I have installed the new certificate on plesk and it is showing in the list of available certificates.
I have then gone to 'IP addresses', selected the required public IP address and selected the new certificate in the dropdown.

When I go then access the IP address at HTTPS, it still gives me the usual security warning and in the browser info, it's still trying to use the old free certificate.

Has anyone got any ideas as to what could cause this and what deep, dark setting I need to change to get it to realise there's a nice shiny new SSL sitting there!?

Thanks,
Matt

Thanks, but unfortunately these are the exact instruction I followed, and it still does not work

If you use an SSL checker like SSL Check to make sure your certificate is installed properly or SSL Checker do they return the details of the certificate you've installed or of a different certificate (if so, which one)?

Hi. They still display the certificate that is securing the domain URL, not the IP address. That's the strange thing

Just to be sure is the certificate selected as the "Certificate for securing Plesk" in Tools & Settings > SSL/TLS Certificates? As shown in this example image.
