thanks for the reply! It is a curious set up, but it has been working fine till it needed renewing.
I do not know why the www certificate has not expired, or indeed, where it is, as I have no record of that in the Cpanel that I can admin.
I assume the issue is within the Digital ocean droplet, the set up of which is above my skill set. The site was developed on the Digital Ocean platform by a developer who has vanished.
I will look into the Digital Ocean set up to see if I can learn more.
You are hosting your main website (fledge.education) from the cPanel server.
However, login.fledge.education is hosted from the DigitalOcean Droplet, not from the cPanel server.
Now, when you want to create an SSL certificate for any of your domains, you need to do it from the server on which the domain is actually hosted.
This means that you can’t create a certificate for login.fledge.education from the cPanel server - the domain isn’t hosted there.
If you want to secure/renew a certificate for login.fledge.education, you need to login to your DigitalOcean droplet via SSH as the root user, and renew it using Certbot or whatever Let’s Encrypt software was used to create the certificate initially.
I hope that sort of makes sense.
Reading in between the lines, it seems like your developer may have left you in a lurch and you might not have the ability to do this on your own. In that case, I’d try find somebody to replace them.
Hello, many thanks, yes that makes sense. I think it was co-incidental that the certificates expired on both servers at the same time. Because a dev version on the site on the Droplet was originally on the C-panel adminsitered server.
