原因是超时，参数相应调大即可解决，均为http块下配置

proxy_connect_timeout 300s; # nginx和后端服务器建立连接的超时时间
proxy_read_timeout 300s; # 连接成功后，后端服务器响应超时时间
proxy_send_timeout 300s; 
proxy_buffer_size 64k; # nginx保存用户头信息的缓冲区大小
proxy_buffers 4 32k; 
proxy_busy_buffers_size 64k; # 高负荷下缓存大小
proxy_temp_file_write_size 64k; 
proxy_ignore_client_abort on; # 不允许nginx主动关闭连接
