Service not exposing in kubernetes - kubernetes

Question

I have a deployment and a service in GKE. I exposed the deployment as a Load Balancer but I cannot access it through the service (curl or browser). I get an:
curl: (7) Failed to connect to <my-Ip-Address> port 443: Connection refused
I can port forward directly to the pod and it works fine:
kubectl --namespace=redfalcon port-forward web-service-rf-76967f9c68-2zbhm 9999:443 >> /dev/null
curl -k -v --request POST --url https://localhost:9999/auth/login/ --header 'content-type: application/json' --header 'x-profile-key: ' --data '{"email":"<testusername>","password":"<testpassword>"}'
I have most likely misconfigured my service but cannot see how. Any help on what I did would be very much appreciated.

Answer 1

I figured out what it was...
My golang app was listening on localhost instead of 0.0.0.0. This meant that port forwarding on kubectl worked but any service exposure didn't work.
I had to add "--host 0.0.0.0" to my k8s command and it then listened to requests from outside localhost.
My command ended up being...
"./server --port 8080 --host 0.0.0.0"
