Issue Let's Encrypt Certificate missing domain name

[davorg]

Server operating system version

AlmaLinux 9.5

Plesk version and microupdate number

18.0.66 Update #2

I'm running Plesk Obsidian Web Host Edition / Version 18.0.66 Update #2 on AlmaLinux 9.5.

Earlier today, I added a new sub-domain to one of the existing domains on the server. And an hour or so later, I added a basic Let's Encrypt certificate to the domain. But the certificate doesn't work properly as the domain name is missing. You can see the Qualys report at SSL Server Test: proxy.davecross.co.uk (Powered by Qualys SSL Labs) and the broken certificate by trying to visit https://proxy.davecross.co.uk/.

I've had this problem before and I can't remember how I have fixed it in the past. Does anyone have any suggestions?

Thanks,

Dave...

How did you installed the certificate? Did you edited the hosting settings and selected a certificate or did you went to SSLTLS Certificates section and installed a new certificate?
