Change internal LAN IP on FortiNet firewall hosted on Azure

Hi memebrs,

This is my first post on this forum plus first time setting up FortiNet UTM on Azure.  After setting up the FortiNet firewall successfully I tried to change the internal NIC IP via the Fort console (GUI). No sooner I apply that change I'm kicked out of the firewall login. Not even the console login. I had to re-deploy the VM from the template again!.

So I'm in my next try now. When you create the FortiNet VM on Azure side Private IP are applied automatically. So wondering if I've to do the internal NIC IP changes from the Azure console or via Foti Console. Anyone faced this issue?
