Golang + nginx + https

I have - Go to the server as a listener http and https. Nginx configured to process incoming requests for http + https. Certificates in order.
Using separate servers runs perfectly on the results of queries to them on https protocol. However, when I use a proxying nginx https is not getting a response from the server and the server Go

> "http: TLS handshake error from 127.0.0.1:54037: tls: first record
> does not look like a TLS handshake

What could be the problem?

Client Go:

package main

import (
	"net/http"
	"log"

)

func HelloSSLServer(w http.ResponseWriter, req *http.Request) {
	w.Header().Set("Content-Type", "text/plain")
	w.Write([]byte("This is an example server.\n"))
	// fmt.Fprintf(w, "This is an example server.\n")
	// io.WriteString(w, "This is an example server.\n")
}

func main() {
	http.HandleFunc("/", HelloSSLServer)
	go http.ListenAndServe("192.168.1.2:80", nil)
	err := http.ListenAndServeTLS("localhost:9007", "/etc/letsencrypt/live/somedomain/fullchain.pem", "/etc/letsencrypt/live/somedomain/privkey.pem", nil)

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

Nginx config:

server {
    listen       192.168.1.2:80;
    server_name   somedomain;
    rewrite ^ https://$host$request_uri? permanent;    
}
server {
    listen        192.168.1.2:443 ssl;
    server_name   somedomain;
    access_log    /var/log/nginx/dom_access.log;
    error_log     /var/log/nginx/dom_error.log;
    ssl_certificate     /stuff/ssl/domain.cert;
    ssl_certificate_key /stuff/ssl/private.cert;
    ssl_protocols       TLSv1 TLSv1.1 TLSv1.2;
    ssl_ciphers         ALL:!ADH:RC4+RSA:+HIGH:+MEDIUM:+LOW:+SSLv2:+EXP;


    location /
    {
        proxy_pass http://localhost:9007;
#       proxy_redirect    http://localhost:1500 http://site1;
        proxy_cookie_domain localhost somedomain;
        proxy_buffering off;

        proxy_http_version 1.1;
        proxy_set_header Host $host;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header Client-IP $remote_addr;
        proxy_set_header X-Forwarded-For $remote_addr;
    }
}

Use https with the proxy_pass

location /
{
    proxy_pass https://localhost:9007;
    ...
}

nginx .config file should like this

server {
        listen 443 ssl http2;
        listen 80;
        server_name www.mojotv.cn;
        ssl_certificate     /home/go/src/my_go_web/ssl/**.pem; 
        ssl_certificate_key /home/go/src/my_go_web/ssl/**.key; 
        ssl_session_timeout 5m;
        ssl_protocols TLSv1 TLSv1.1 TLSv1.2;
        ssl_ciphers AESGCM:ALL:!DH:!EXPORT:!RC4:+HIGH:!MEDIUM:!LOW:!aNULL:!eNULL;
        ssl_prefer_server_ciphers on;
        location /(css|js|fonts|img)/ {
            access_log off;
            expires 1d;
            root "/home/go/src/my_go_web/static";
            try_files $uri @backend;
        }
        location / {
            try_files /_not_exists_ @backend;
        }
        location @backend {
           proxy_set_header X-Forwarded-For $remote_addr;
           proxy_set_header Host $http_host;
           proxy_pass http://127.0.0.1:********;
        }
        access_log  /home/wwwroot/www.mojotv.cn.log;## nginx log path
}

the golang web app with http2 ssl feature shiped with nginx

I get a similar error message to OP for a more basic Go server that doesn't have extra config.

> tls: first record does not look like a TLS handshake

My temp fix was simply to make sure the test URL includes both "https://" and the port number in the URL.

didn't work - ipaddress

didn't work - https://ipaddress

worked - https://ipaddress:8081

It'll do for testing, until a more advanced setup. Just posting this to help others in troubleshooting.
