Answer 1

As you pointed out, looks like nginx is proxying your https request to ipWhichEndsWith.249:8443, which is an HTTPS endpoint, using http as protocol.

You should add the following annotation to your PodSpec:

LATEST

This annotation was added to replace the deprecated annotation since 0.18.0

#2871 Add support for AJP protocol

nginx.ingress.kubernetes.io/backend-protocol: "HTTPS"

---

DEPRECATED

This annotation was deprecated in 0.18.0 and removed after the release of 0.20.0

#3203 Remove annotations grpc-backend and secure-backend already deprecated

nginx.ingress.kubernetes.io/secure-backends: "true"

---

This should make nginx forward your request to the pods with https.
