GoDaddy SSL Certificate

I have spent entirely too much time trying to install a GoDaddy-issues cert on an OpenFire server ( running on Ubuntu ).

I have installed the Cert Manager plugin and when I try to import the cert, I get this error:
There was an error while trying to import the private key and signed certificate. Internal server error: The supplied certificate chain does not cover the domain of this XMPP service.

Any help would be greatly appreciated as I am about ready to lose my mind.
