CWPpro terminal ERROR: hostname not set.

When I try to login to CWPpro terminal I got this error:

"ERROR:To use the terminal it is necessary to have a valid hostname configured"

I must admit I have been struggling quite a bit on how to set up the hostname. But finally got it right.. err..
untill I got that error.. it clearly is not.

I have set the hostname as a subdomain A record in mydomains DNS zone. : host.mydomain.com.

I also gives me the option(link) to set a new hostname, but that screws up the SSL settings!

This is my DNS Zone record:

English is not my first language, so forgive me for misspelling.

I can't help but notice that your domain says .cum, not .com, that COULD be the issue, if that isn't it, then I sadly do not know, i am in the same boat with my own server.
