error secure connection failed in ingress controller

Question

I am using the default Ingress controller (nginx for minikube) and have successfully enabled ingress:

minikube addons enable ingress

ingress config YAML (basic-ingress.yaml):

apiVersion: extensions/v1beta1
kind: Ingress
metadata:
  name: basic-ingress
spec:
  backend:
    serviceName: nginx
    servicePort: 80

And now applying the YAML:

kubectl apply -f basic-ingress.yaml

Verify the Ingress

kubectl get ingress basic-ingress

Output:

NAME            HOSTS     ADDRESS         PORTS     AGE
basic-ingress   *         192.168.64.37   80        16s

Visit the Application

When I point my browser to the site (http://192.168.64.37) is tries to convert to https which gives an error "secure connection failed" (from Firefox, but similar error from Chrome) owever, when I curl the site I get the "301" error:

curl 192.168.64.37

Output:

<html>
<head><title>301 Moved Permanently</title></head>
<body bgcolor="white">
<center><h1>301 Moved Permanently</h1></center>
<hr><center>nginx/1.11.12</center>
</body>
</html>

Nginx ingress tries to redirect to an https protocol i.e. port 443. But in case its not configured it throws this error “301 moved permanently”.

I set the ssl-redirect flag as follows

apiVersion: extensions/v1beta1
kind: Ingress
metadata:
  name: basic-ingress
  annotations:
    ingress.kubernetes.io/ssl-redirect: "false"
spec:
  backend:
    serviceName: nginx
    servicePort: 80
