我在ECS服务器上运行docker-nginx.我的nginx服务突然停止,因为其中一个服务器的proxy_path无法访问.错误如下:

[emerg] 1#1: host not found in upstream "dev-example.io" in /etc/nginx/conf.d/default.conf:988

我的配置文件如下:

 server {
       listen      80;
       server_name     test.com;
       location / {
          proxy_pass         http://dev-exapmle.io:5016/;
          proxy_redirect     off;

          ##proxy_set_header   Host             $host;
          proxy_set_header   X-Real-IP        $remote_addr;
          proxy_set_header   X-Forwarded-For  $proxy_add_x_forwarded_for;

          client_max_body_size       10m;
          client_body_buffer_size    128k;

          proxy_connect_timeout      90;
          proxy_send_timeout         90;
          proxy_read_timeout         90;

          proxy_buffer_size          4k;
          proxy_buffers              4 32k;
          proxy_busy_buffers_size    64k;
          proxy_temp_file_write_size 64k;
       }
}

server {
   listen       80 default_server;
   server_name  localhost;
