Problem z Flarum

Bez%C2%A0tytu%C5%82u|690x431 Podczas wejścia na stronę instalacji Flarum mam takie błędy. Używam nginx'a i to mój plik w sites-available:

server {

    server_name nazwa.ml www.nazwa.ml;
    root /var/www/html/nazwa;

    index index.php index.html index.htm;
    location / {
            try_files $uri $uri/ /index.php?$query_string;
    }

listen [::]:443 ssl http2 ipv6only=on; # managed by Certbot
listen 443 ssl http2; # managed by Certbot
gzip off;
ssl_certificate /etc/letsencrypt/live/www.nazwa.ml/fullchain.pem; # managed by Certbot
ssl_certificate_key /etc/letsencrypt/live/www.nazwa.ml/privkey.pem; # managed by Certbot

include /etc/letsencrypt/options-ssl-nginx.conf; # managed by Certbot
ssl_dhparam /etc/letsencrypt/ssl-dhparams.pem; # managed by Certbot

location ~ \.php$ {
   include snippets/fastcgi-php.conf;
   fastcgi_pass             unix:/var/run/php/php7.1-fpm.sock;
   fastcgi_param   SCRIPT_FILENAME $document_root$fastcgi_script_name;
}

server { if ($host = www.nazwa.ml) { return 301 https://$host$request_uri; } # managed by Certbot

    listen 80 default_server;
    listen [::]:80 default_server ipv6only=on;

    server_name www.nazwa.ml nazwa.ml;
return 404; # managed by Certbot

}
