I'm using Go-micro, Docker, Traefik to deploy my service. I deployed go-micro service and registered with Traefik. This is my sum(grpc service) status in Traefik dashboard. When i curl it in Terminal, I got this result, I thought it's grpc message in binary. But when I used this code 

package main

import (
    "context"
    "fmt"
    proto "gomicro-demo/client/service"
    "google.golang.org/grpc"
    "google.golang.org/grpc/metadata"
    "log"
)

func main() {


    con, err := grpc.Dial("localhost:8080", grpc.WithInsecure())

    if err != nil {
        log.Fatal("Connection error: ", err)
    }

    md := metadata.New(map[string]string{"Host": "sum.traefik"})
    ctx := metadata.NewOutgoingContext(context.Background(), md)

    service := proto.NewSumClient(con)
    res, err2 := service.GetSum(ctx, &proto.Request{})

    if err2 == nil {
        fmt.Println(res)
    } else {
        log.Fatal("Call error:", err2)
    }

}

i got this error rpc error: code = Unimplemented desc = Not Found: HTTP status code 404; transport: received the unexpected content-type "text/plain; charset=utf-8". I can't know how this error happen, because of address or grpc metadata (Host header). Please help me with this problem. Thank you very much!

you can export tcp like it. please using trefik2, HostSNI must be seted

apiVersion: traefik.containo.us/v1alpha1
kind: IngressRouteTCP
metadata:
  name: redis
spec:
  entryPoints:
    - redis
  routes:
  - match: HostSNI(`*`)
    services:
    - name: redis
      port: 6379
