Help - newbie question ---- nodeport not showing

I cannot see the nodeport on the workload summary page … below my apps it doesnt show the nodeport port number ie … tcp/31000.
This is even thought i follow the example of rancher … in configuring the app Portmapping…
publish container port : 80 , Protocol: TCP , As a: NodePort, Listening:31000.

On the server I have even disable firewall and did a netstat but stiil cannot find port 31000.
Is this a rancher security or have i miss some steps.

:frowning: please help…should be an easy issue , tearing my hair out.
