I have set up the Nginx-Ingress controller as per the documentation (Installation guide)and followed the steps using the example provided. When I try to access the service using the curl command, I am getting a 400 Bad request. When I look at the logs of the nginx-ingress pod, I am not seeing any error. I have attached the logs for reference. I am finding difficult to troubleshoot the issue. Where
fetch the pods from the nginx-ingress namespace
$ kubectl get po -n nginx-ingress
