Last week we tried to install Drupal by using the default template for Drupal 8 + MySql database in Azure (using drupal-nginx-fpm:0.1, Linux environment). However, we bumped up to an issue where after an X time Drupal isn't responding (502/503 error in browser) by the following error in the logging.
An AJAX HTTP error occurred.
HTTP Result Code: 200
Debugging information follows.
Path: /drupal8./core/install.php?rewrite=ok&langcode=pt-br&profile=standard&continue=1&id=1&op=do_nojs&op=do
StatusText: OK
ResponseText:
Fatal error: Maximum execution time of 30 seconds exceeded in C:\xampp\htdocs\drupal8\core\lib\Drupal\Core\Database\Statement.php on line 59
