Default site configured for 444 returns 404

[Steinar Bang]

Ok, found it!

Turned out one of my other configs (the server www.mycompany.com one)
had this
server {
        # SSL configuration
        #
        listen 443 ssl default_server;
        listen [::]:443 ssl default_server;
        ssl_certificate     /etc/letsencrypt/live/www.mycompany.com/fullchain.pem;
        ssl_certificate_key /etc/letsencrypt/live/www.mycompany.com/privkey.pem;

        server_name www.mycompany.com;
}

so what I did, was:

 1. Remove the " default_server" from the www.mycompany.com server:
     server {
             # SSL configuration
             #
             listen 443 ssl default_server;
             listen [::]:443 ssl default_server;
             ssl_certificate     /etc/letsencrypt/live/www.mycompany.com/fullchain.pem;
             ssl_certificate_key /etc/letsencrypt/live/www.mycompany.com/privkey.pem;

             server_name www.mycompany.com;
     }


 2. Add SSL listening for default_server to the default config:
     server {
             listen 80 default_server;
             listen [::]:80 default_server;
             listen 443 ssl default_server;
             listen [::]:443 ssl default_server;
             ssl_certificate     /etc/letsencrypt/live/www.bang.priv.no/fullchain.pem;
             ssl_certificate_key /etc/letsencrypt/live/www.bang.priv.no/privkey.pem;

             server_name _;

             return 444;
     }

After this, all IP number accesses to my server on either port 80 or
port 443, are met with 444.
