Instale o Sonerezh como um subdomínio no Nginx

ao instalar o Sonerezh me indica que não encontra instalar. Coloquei o código de configuração do subdomínio musica:

server {
            ## Escucha en el puerto 80 (HTTP)
            listen 80;

            server_name musica.dominio.com;

            location / {
                    return 301 https://$server_name$request_uri;
            }
}
