-backend:80 (<error: endpoints "default-http-backend" not found>

Hello KodeKloud

When I am trying to create an ingress resource for my Kubernetes cluster(ingress controller is already created), Ingress resource/rules is creating and I am able to see in the kubectl get ing. But when I do kubectl describe , I am seeing a error: Default backend: default-http-backend:80 (<error: endpoints “default-http-backend” not found>). Is this expected?? I am not even able to connect to my application using the DNS name (hotel.example.com) which I defined in Ingress resource. is it due to this http backend error?? If not any suggestions to make the application connect!!
