User not permitted from this IP address - 4

Hi,

I am setting up domain mapping and can't get the re-seller option to work with enom.

I have created an enom account (through the Network Admin dashboard link in the plugin) and I had enom add my IP.

I can log into my enom account when I visit their site, but my credentials aren't working inside Domain Mapping.

I keep getting this error: User not permitted from this IP address - 4

Any ideas?

Thanks
