Getting connection timeout when doing nginx reverse proxy to kubernetes ingress. Not getting what is wrong here
Running minikube --driver=docker
2021/12/21 23:52:25 error 7#7: *6 upstream timed out (110: Connection timed out) while connecting to upstream, client: 10.227.224.11, server: , request: "GET / HTTP/1.1", upstream: "http://192.168.49.2:80/", host: "10.105.230.34:8089"
-bash-4.2$ kubectl get ingress
NAME CLASS HOSTS ADDRESS PORTS AGE
ingress-service <none> * 192.168.49.2 80 12h
-bash-4.2$
But when I do a curl I get the response
Also the curl works only when I do export no_proxy=$no_proxy,$(minikube ip)
bash-4.2$ curl http://192.168.49.2:80/

Ingress defn:
apiVersion: networking.k8s.io/v1
# UPDATE API
kind: Ingress
metadata:
name: ingress-service
annotations:
kubernetes.io/ingress.class: 'nginx'
#nginx.ingress.kubernetes.io/use-regex: 'true'
# ADD ANNOTATION
#nginx.ingress.kubernetes.io/rewrite-target: /$1
# UPDATE ANNOTATION Any pointers how to debug this.
Update: when i use port forwarding like below I am able to reach the application
sudo firewall-cmd --add-forward-port=port=8089:proto=tcp:toport=80:toaddr=192.168.49.2
