Nginx

Problem with nginx config. Config:
server {
listen 80;
server_name vim.domain.ru;
root /usr/local/vimbadmin/public;
index index.php;
access_log /var/log/nginx/vim.access.log;
error_log /var/log/nginx/vim.error.log;
location / {
try_files $uri $uri/ /index.php?$args;
}
location ~ \.php$ {
try_files $uri =404;
fastcgi_intercept_errors on;
fastcgi_pass unix:/var/run/sock/php5-fpm.sock;
}
location ~* \.(js|css|png|jpg|jpeg|gif|ico)$ {
expires max;
log_not_found off;
}
}

Loading a web page at vim.domen.ru caused too many redirects. Try clearing cookies for this server or allowing them to be accepted from third party sites. If that doesn't help, the problem might not be with your computer, but with the server's configuration.
