Gateway Timeout

  • 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.

Artisan syntax error

Problem:

  • PHP Parse error: syntax error, unexpected ‘class’ (T_CLASS), expecting identifier (T_STRING) or variable (T_VARIABLE) or ‘{‘ or ‘$’ in …/artisan on line 31
  • $kernel = $app->make(Illuminate\Contracts\Console\Kernel::class);

Solution:

::class is only available from PHP 5.5 onward, So updating php version of the SERVER will solve the problem.

First check php version of your server with command line.

php -v

Note that phpinfo() may give different version that with the php -v
