nginx net :: ERR_INCOMPLETE_CHUNKED_ENCODING

Question

我试图在nginx上找到一个代理到Netty的URL，对于一个特定的URL，我在chrome上获取net :: ERR_INCOMPLETE_CHUNKED_ENCODING，而在Safari上有时它会工作，有时则没有。

Here is the configuration: 
location /service-order-api {
    proxy_http_version 1.1;
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_set_header Host $http_host:$server_port;
    proxy_pass http://service_order_api;
    #proxy_read_timeout 120;
    proxy_set_header X-Real-IP $remote_addr;
    #proxy_buffer_size 2k;
    #proxy_buffers 8 24k;
    proxy_redirect off;
    #proxy_buffering off;
    chunked_transfer_encoding on;
  }
