Magento 2.3.6 stuck in loading and doesn't load any page

[jawadrashef2af]

I have a Magento 2.3.6 app which was working fine and suddenly It stop responding. It keeps loading for like 5 minutes and then errors out with 504-Bad Gateway Timeout. I have already tried the following solutions without any luck:

• Increase PHP max execution time and memory limit
• Change server
• Even changed my machine
• Delete and reinstall composer dependencies
• run Setup: install and Setup: upgrade commands

I have also turned on Developer mode and put these lines at the start of `index.php` to enable error in browser but not getting any error either

error_reporting(E_ALL);
ini_set('display_errors', 1)

Any clue How I can solve this? Thanks in advance.

I have the exact same issue with Magento 2.3.6-p1 using PHP 7.3.

Pages simply don't load, there does not seem to be any error message anywhere.

Hi @jawadrashef2af,

The error that you're facing might be due to: 

(1) Hosting Error 

You should contact your hosting provider to check if there's any problem. 

(2) Your site is running a command or requirement that takes too much time. You can check it by turning on the dev mode: 

php bin/magento deploy:mode:set developer

Hope this can help you! Let me know if you need further assistance.
