master_domain_ipv4: This input is required

I have imported a couple domains using import.pex, now next two domains fail with following error message:
master_domain_ipv4: This input is required

I am importing from cPanel with following command lines:
su iworx
/home/interworx/bin/import.pex --archive=/cp/man.tar.gz --ip-address=102.52.182.102 --control-panel=cpanel --force

Any ideas what I am doing wrong?

Hmm, now I am getting:
IP not available to InterWorx: 102.52.182.102

The test site I configured on InterWorx is on that IP address, very odd

Doggone it…

I had the IP address set to dedicated instead of SHARED
