nginx 反向代理 端口 安全组

Question

location /api/ {
                proxy_pass http://服务器IP:8000/api/;
                proxy_set_header X-Forwarded-Proto $scheme;
                proxy_set_header X-Forwarded-Port $server_port;
                proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
                proxy_set_header Upgrade $http_upgrade;
                proxy_set_header Connection "upgrade";
        }

nginx给springboot的8000端口做代理，为什么在安全组中必须把8000端口开放才可以，关了就无法访问了，请教大神们
