我在我的DigitalOcean droplet上设置了两个Web应用程序，现在我想在不同的域名下运行这两个应用程序，并且使用SSL加密。
如果我只使用其中一个域名，我可以确认一切正常，但当我尝试同时运行两个应用程序时，就会出现错误。
nginx -t

/etc/nginx/sites-avilable/hello.com
server {

location / {
proxy_pass http://localhost:4000;
proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection 'upgrade';
proxy_set_header Host $host;
proxy_cache_bypass $http_upgrade;
}

我该怎么避免这个错误？非常感谢您进一步完善nginx文件。
