"Server temporarily unavailable" with new 2.2.0 On-Premises instance

I just spinned a new cnmaestro with 2.2.0 OVA file.
I have configured the IP.

I tried logging in with the IP and its saying server temporarily unavailable.

Kindly assist

It can take a while the first time out of the gate. Keep refreshing. If it is still happening after about 10 minutes, the must be another issue.
