I've got a problem with ingress-nginx. Which is working if I access the host publicly. However, accessing the host from within the cluster seems to fail. PS: I installed nginx-ingress as DigitalOcean one-click install suggestion. But I don't think the problem has in DO. I've been trying find and solve this issue for last 3 days.

I tested it by SSLPoke, got same result. This is testing it within as cluster.

the result from curl in pod (within cluster), but when i check it publicly it's working right:

the configuration in digitalocean loadbalancer
