proxy_read_timeout has default value '60'. According official documentation you can set it for all server and per vhost (http://nginx.org/en/docs/http/ngx_http_proxy_module.html#proxy_read_timeout). Create vhost_nginx.conf in conf directory of your domain with 'proxy_read_timeout 600;' content. Don't forget reconfigure domain - /usr/local/psa/admin/sbin/httpdmng --reconfigure-domain example.com
