PHP：狂饮6-cURL错误7连接被拒绝

我进行了搜索,并阅读了http://docs.guzzlephp.org/en/stable/request-options.html处的文档,并确认了https://curl.haxx.se/libcurl/c/libcurl-errors.html处的错误,并且对我而言,我无法弄清楚发生了什么.我的/ etc / hosts文件中有app-one和app-two的URL,我知道它们是正确的,因为我可以在浏览器中通过终端通过cURL来访问它们.

我的设置：

Docker容器配置为：

App 1 = php-fpm - responding app
App 2 = php-fpm - requesting app,using Guzzle 6.3.2
Nginx Reverse Proxy

nginx配置：
