Answer 1

Seu log descreve:

Mar 11 11:21:13 server nginx[1104]: nginx: [emerg] "fastcgi_pass" directive is duplicate in /etc/nginx/sites-enabled/def

Mar 11 11:21:13 server nginx[1104]: nginx: configuration file /etc/nginx/nginx.conf test failed

Seu arquivo de configuração não é válido, contém algum erro ("diretiva fastcgi_pass é duplicada"). Verifique e corrija!
