Nginx "rewrite or internal redirection cycle while internally redirecting to "/index.html"

So here is my problem: I have the same problem with every file I try to access. It always sends me back to index.html or shows me an 500 server error. The error log gives me: "rewrite or internal redirection cycle while internally redirecting to "/index.html"

here is my config:

server { listen 80; root /var/www; index index.php index.html index.htm; server_name _; location / { try_files $uri $uri/ /index.html; } error_page 404 /404.html; error_page 500 502 503 504 /50x.html; location = /50x.html { root /var/www; } # pass the PHP scripts to FastCGI server listening on the php-fpm socket location ~ \.php$ { 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; } 

Whats the problem?
