• Gateway Timeout
• The gateway did not receive a timely response from the upstream server or application.
• The timeout specified has expired
• Fatal error: Maximum execution time of 300 seconds exceeded

It could be max_execution_time or max_input_time in .

This can usually be resolved by increasing the values for:

• max_execution_time and/or max_input_time in the php.ini (DirectAdmin: /usr/local/lib/php.ini) and
• fastcgi_read_timeout in /etc/nginx/nginx_limits.conf

Restart php-fpm and nginx after the changes

or

Open httpd.conf and add

TimeOut 120
ProxyTimeout 120

Solve the issue in WAMP and XAMPP

To increase the max_execution_time

1. Go to C:\wamp\apps\phpmyadmin\libraries (path according to your installation)
2. Open config.default.php and change value for $cfg[‘ExecTimeLimit’] to 0:

   $cfg['ExecTimeLimit'] = 0;

This will resolve the issue for PhpMyAdmin imports.
