Thanks.
To be clear, if I cannot find a ref to the cert I intend to delete in the webserver config then I'm good to go? No other applications like email servers will be using that certificate?
How do I check or find out what might be using one of those certificates?
Thanks

Hard for me to know what's going on inside your server.
Does that server have other services that are (or can be) TLS secured?

Thanks.
Like what sort of services? If you can suggest what I should look for, I'll check.

Maybe you can run
sudo ss -tlp
and see if any programs on the server are running publicly-accessible services (local address other than 127.0 IPv4 network or [::1] IPv6 network).
The most common TLS services other than HTTPS are e-mail-related protocols (if your server is an e-mail server).

This is what I'm thinking. It might be postfix that's using one of those other certificates.
I'll try this and let you know what emerges!
