我的Nginx有问题。如果我使用节点提供我的页面和文件，一切正常，但如果我使用Nginx，在我快速刷新我的网站几次后，我会收到停滞的请求和消息“等待可用的套接字”＃39; 问题在于Chrome提供给我们的ssl_socket_pool和最大连接数为6。完成后如何关闭这些连接。我应该如何设置我的nginx以及为什么不使用Nginx时没有问题？
这是我的Nginx配置

# # - Enable open file cache
# nginx can cache static files for a short period of time. Adding this within your configuration block tells nginx to cache 1000 files for 30 seconds, excluding any files that haven’t been accessed in 20 seconds, and only files that have been accessed at least 2 times in that timeframe. However, it also means that the server won't react immediately to changes on disk, which may be undesirable
