This is driving me crazy for couple of days now, trying to find the solution. I'm running a script and I get "Gateway Timeout" errors after 5 minutes (300s). I checked and changed every parameters I could find: /etc/php/7.3/fpm/php.ini /etc/php/7.3/apache2/php.ini /etc/php/7.3/cgi/php.ini /etc/php/7.3/cli/php.ini to max_execution_time = 3000 max_input_time = 3000 I also entered that parameters to Custom php.ini settings in ISPC site options. Next I tried to change: in /usr/local/ispconfig/server/conf/vhost.conf.master: <tmpl_if name='fastcgi_config_syntax' op='==' value='2'> FcgidIdleTimeout 3000 Current setup: Ispconfig 3.2.12p1 Debian Buster (at this moment no option to upgrade) Apache, custom PHP versions On website I have enabled PHP-FPM (PHP 7.3 is used due to interbase / firebird module). I also wrote a test.php script, which terminates after 5min <?php set_time_limit(0); while(1) { sleep(10); } ?>Phpinfo also shows all values correctly, "3000" What am I missing? I checked every known configuration file and I can't find any parameter that would limit execution time to 5min.
