Hi,
I have successfully installed my app on Kubernetes cluster. But I observed my app was seeing the local IP instead of actual client IP. So I enabled proxy protocol in load balancer and installed nginx-ingress as follows:
# Installing the Kubernetes Nginx Ingress Controller
helm install stable/nginx-ingress --name nginx-ingress --set controller.publishService.enabled=true,controller.config.use-forwarded-headers='"true"',controller.config.use-proxy-protocol='"true"'
But now I get the following error on accessing my API:
curl https://my-api.example.com/v3/status
curl: (35) error:1400410B:SSL routines:CONNECT_CR_SRVR_HELLO:wrong version number

Hello,
Just came across this answer and decided to write some general guidelines for anyone who comes across this in the future despite the old question.
It seems like there’s an issue with your SSL/TLS configuration. Based on the error message, it may be due to a mismatch between the supported protocol versions on the client and server side. You should check your Nginx Ingress configuration to ensure that it’s set up to handle SSL/TLS correctly.
Here’s what you may do:
- Verify that your secret containing the TLS certificate and key is correctly configured and mounted in the Ingress resource.
- Check the logs of your
nginx-ingress-controllerpod for errors or warnings about your TLS configuration. - Update your Nginx Ingress Controller if you are using an older version, as it may have limited compatibility with newer TLS versions.
For more details on troubleshooting Nginx Ingress, refer to this DigitalOcean tutorial on configuring Nginx Ingress with Cert-Manager.
Hope that this helps!
