You need to get a copy of your intermediate certificate authority's
certificate (in your case, that Go Daddy Secure Certificate Authority
- - G2 or probably https://certs.godaddy.com/repository/gdig2.crt, check
https://certs.godaddy.com/repository to make sure) and concatnate it
at the end of your mydomainname.crt.

This way you are presenting a chain of certificate (your certificate,
then intermediate certificate that have signed your certificate; you
don't need to include the root certificate as it's a waste of
bandwidth) to the client.
