gRPC AWS Ingress Kubernetes - amazon-web-services

Question

I am trying to set up an Ingress manifest that allows traffic through an ALB to connect to a gRPC pod. I am currently getting the error:
{
"error": "14 UNAVAILABLE: Trying to connect an http1.x server"
}
Not really sure what this means as I am new to gRPC. I am using BloomRPC to test this currently by hitting dns-of-alb:50051
