Unable to allocate IP address for certificate

I get this notification when I go through these steps 1). creating/installing a site without ssl, 2) then trying to enable ssl. After enabling SSL on the site and clicking save I get the message, "Unable to allocate IP address for certificate, disabling SSL. Allocate more IP addresses to this server then try to enable SSL again." The site saves but does not enable ssl. I think it is related to not allocating an IP address but only the host name. This seems to fix it:
