# blog/index.php/legacy-path to continue to route to Drupal nodes. If
# you do not have any paths like that, then you might prefer to use a

# pattern with front controllers other than update.php in a future

O FastCGI também estava recebendo conexão recusada se especificado como fastcgi_pass unix:/var/run/php7.0-fpm.sock; .
A única desvantagem que tenho agora é que não consigo baixar nenhum módulo / tema através da seção Estender, mas isso é apenas um problema de permissão de pasta.
