Question
Enabled proxy protocol in load balancer causing CONNECT_CR_SRVR_HELLO:wrong version number error
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
Hi there!
Can you check to ensure your service is configured properly to use proxy protocol via the DO LB: https://www.digitalocean.com/docs/kubernetes/how-to/configure-load-balancers/
