You'll have to update the CA store on the server - check the version of Mozilla::CA installed.

It seems you may be right after all hippo!

Is updating the CA store on the server something I can do on shared hosting or do I have to get the server admins to do it? I am able to install new certificates and historically I have had to until, earlier this year, they arranged for Lets Encrypt to automagically renew them.

The Mozilla::CA version is 20120823
I assume that's a date - a very old date!

UPDATE:
I've answered my own question - I can sort of update the CA store...

cPanel has two places for modules. Server wide modules and user level modules. I can, and have, done the update at a user level. To use this version instead of the server wide module I have to have use cPanelUserConfig; before I use any modules that rely on the CA store being up to date.
