Необъяснимый редирект nginx

Не понимаю, почему nginx перенаправляет на основной домен с поддомена, имея явную конфигурацию:

    server {
    server_name launcher.myprod.com;
    ssl_certificate /etc/letsencrypt/live/launcher.myprod.com/fullchain.pem;
    ssl_certificate_key /etc/letsencrypt/live/launcher.myprod.com/privkey.pem;
    add_header Strict-Transport-Security "max-age=31536000;";
    include /etc/letsencrypt/options-ssl-nginx.conf;
    ssl_dhparam /etc/letsencrypt/ssl-dhparams.pem;
    index index.php index.html;
    disable_symlinks if_not_owner from=$root_path;
    ssi on;
    set $root_path /var/www/launcher.myprod.com;
    root $root_path;
    listen 80;
    listen 443 ssl;
    location / {
        root /home/launcher/5171/updates;
    }
    location /api {
        proxy_pass http://localhost:9274/api;
        proxy_set_header Host $host;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_connect_timeout     100;
        proxy_send_timeout        100;
        proxy_read_timeout        100;
        send_timeout              100;
    }
}

launcher.myprod.com ==> myprod.com ==> error
