I have iRedMail on a VPS. It works. It is hosted on mail.mydomain.com. I added another website configuration to /etc/nginx/sites-available and did the symbol link to /etc/nginx/sites-enabled and I restarted nginx. But the website doesn't work.

Here is the nginx configuration titled "mydomain.com.conf":
server {
    listen        80;
    server_name   mydomain.com;
    location / {
        proxy_pass         http://localhost:5000;
        proxy_http_version 1.1;
        proxy_set_header   Upgrade $http_upgrade;
        proxy_set_header   Connection keep-alive;
        proxy_set_header   Host $host;
        proxy_cache_bypass $http_upgrade;
        proxy_set_header   X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header   X-Forwarded-Proto $scheme;
    }
}

This is an ASP.NET Core website. This is where I got information for hosting on linux https://docs.microsoft.com/en-us/aspnet … etcore-3.1

What did I do wrong?
