For Nginx as Proxy (php-fpm disabled)

To apply settings globally, increase the following timeout values by adding the file /etc/nginx/conf.d/timeout.conf and restarting 'nginx' service:

# cat /etc/nginx/conf.d/timeout.conf

proxy_connect_timeout 600;
proxy_send_timeout 600;
proxy_read_timeout 600;
send_timeout 600;

If you only are able to increase timeout settings per domain, it can be done in this way:

Plesk > Subscriptions > my.domain.com > Websites & Domains > Web Server Settings - add the lines to Additional Nginx directives


For Nginx + FastCGI (php-fpm enabled)

Increase max_execution_time setting:

Plesk > Subscriptions > test.com > Websites & Domains > test.com > PHP Settings - Set max_execution_time = 300

Change request_terminate_timeout parameter (commented by default) in /etc/php-fpm.d/www.conf (for Debian /etc/php5/fpm/pool.d/www.conf) file:

request_terminate_timeout = 300

Add fastcgi_read_timeout variable inside the 'nginx' virtual host configuration:

Plesk > Subscriptions > my.domain.com > Websites & Domains > Web Server Settings > Additional Nginx directives

fastcgi_read_timeout 300;

Add/increase the following values in the 'http' section of the /etc/nginx/nginx.conf file:

fastcgi_buffers 8 128k;
fastcgi_buffer_size 256k;

Restart both 'apache' and 'nginx'.
