My domain has a valid certificate, but Openfire uses something else

I’m sure this is self inflicted. I hope someone can help me out.

I have an Ubuntu server 16.04.1

Running Openfire 4.04

I have a valid certificate issued by Let’s Encrypt Authority X3

Web services and other programs on the server use that certificate and they all perform as expected.

When I use secure connections to openfire it pulls up an invalid certificate issued by the server.

How do I get Openfire to use the legitimate certificate?

My spark clients all connect with no issues, but when I try to use the secure console, or Openfire meetings, I get certificate errors.
