Issue Let's Encrypt Not Securing Plesk (8443)

Mark Bailey

Basic Pleskian
Hi,

I used Let's Encrypt to create an SSL certificate for the hostname, which is in the format bb.domain.com. I set the system to use that certificate to secure Plesk itself. If I go to the server's hostname alone in a web browser, I get the default page and the browser says "secure". It shows a certificate from Let's Encrypt. But if I go to bb.domain.com:8443, I get a security warning that the certificate is not trusted. And the certificate info doesn't show Let's Encrypt, it looks like the self-signed cert.

So, the certificate is installed and valid, but doesn't work when accessing Plesk via 8443. What can I do?

Thanks,

Mark
