Nginx no subdomínio: Se o índice for .html, erro 403 proibido se o índice for .php for baixado

Isso só acontece comigo em um subdomínio, no resto funciona bem:

Se o índice sua extensão for htm ou html dá erro:

"403 proibido"

Se o índice sua extensão for php tenta baixar.

As permissões dentro de /srv/www são as mesmas para todos os subdomínios e funcionam.

Coloquei a configuração conf:

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

            server_name musica.domain.com;

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


server {
    ## Escucha en el puerto 443 (HTTPS)
    listen 443 ssl http2;

    server_name musica.domain.com;

    ## Certificados
    ssl_certificate /etc/letsencrypt/live/musica.domain.com/fullchain.pem;
    ssl_certificate_key /etc/letsencrypt/live/musica.domain.com/privkey.pem;
    include snippets/ssl-params.conf;

    access_log  /var/log/nginx/musica_access.log;
    error_log   /var/log/nginx/musica_error.log;

    root /srv/www/sonerezh;

    index index.html index.htm index.php;

    location ~ /.well-known {
            allow all;
    }

    location / {
#              try_files $uri $uri/ /index.php?$args;
    }

    location ~ \.php$ {
            fastcgi_split_path_info ^(.+\.php)(/.+)$;
            fastcgi_pass unix:/var/run/php/musica.sock;
            #fastcgi_param PATH_TRANSLATED $document_root$fastcgi_script_name;
            fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
            fastcgi_index index.php;
            include fastcgi_params;
    }
}

O nginx -Tcomando me mostra que você está realmente lendo o arquivo de configuração do subdomínio.
