nginx没有重定向端口

Question

我已设置域名以将A记录指向我的VPS IP＆amp;添加了以下文件/etc/nginx/conf.d/custom.conf。

server {
    listen 80;
    server_name researchnot.es .researchnot.es;

    location / {
        proxy_pass http://127.0.0.1:8000;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header X-Forwarded-Proto https;
        proxy_set_header X-Forwarded-Port 443;
        proxy_set_header Host $host;
    }
} 

我已经运行service nginx configtest，表示一切正常并重新启动nginx。
