Nginx：（111：接続が拒否されました）上流に接続中

Question

リバースプロキシとしてNginxを使用しようとしています。私はGolangのAPIを呼び出すとき、私は/var/log/nginx/error.logにこのメッセージが表示ポート3334.上のポート3333とGolangアプリの1つのNode.jsアプリを持っている：

2016/07/15 10:18:36 [error] 4835#0: *131 connect() failed (111: Connection refused) while connecting to upstream,

私はからの問題だか分かりません。たぶん私はNginxの設定でいくつかの間違いをしている。ここに私のnginxの構成は次のとおりです。

listen 80; 
server_name video1.techmaster.vn www.video1.techmaster.vn;

Answer 2

に動作します。

私は3000ポートを使用してアプリケーションを起動しました。 私のポートを8081に変更したとき、それは機能しました。
