I cannot get iManager to work on my NW6 SP2 with BM37 SP1 and ZfD 3.2

When I try to go to the serverip:2200 address, I get a black box in
broswer window and the title bar says "you can't go there".

I have checked the hosts file on the server and the NCP exclusion in server parameters.

The local hosts file has an entry for the server ip with the
for workstation importing. Could this be the problem?

What else am I missing?
