GCE ingress resource is taking too long to receive an IP address in GKE cluster. What could be the reason? - kubernetes

Question

I am trying to deploy a sample application on GKE cluster. All the resources are getting created successfully except the ingress resource which is taking around 15-20 minutes to receive an ip address. By this time application times out and get in errored state. The ideal time to assign the IP addr is 2-3 minutes. Can anyone help on the issue how to debug it?
This is happening specific to a cluster while the same ingress getting the ip within 2 minutes in other clusters in GKE.
Below the manifest files I am using to deploy app:
