php + nginx = 500 error, help fix please

Hello. Followed the tutorial https://www.digitalocean.com/community/tutorials/how-to-install-linux-nginx-mysql-php-lemp-stack-on-ubuntu-12-04

Wall went well.

But when i try to run my project i get(nginx error.log) *16 rewrite or internal redirection cycle while internally redirecting to “/index.html”

my server block:

server { listen 80;

    root /var/www/project/public;
    index index.php index.html index.htm;

    server_name myip;

    location / {
            try_files $uri $uri/ /index.html;
    }

    error_page 404 /404.html;

    error_page 500 502 503 504 /50x.html;
    location = /50x.html {
          root /var/www/project/public;
    }

    # pass the PHP scripts to FastCGI server listening on the php-fpm socket
    location ~ \.php$ {
            try_files $uri =404;
            fastcgi_pass unix:/var/run/php5-fpm.sock;
            fastcgi_index index.php;
            fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
            include fastcgi_params;
