SIte is down and showing the 504.

[Shwetab55]

Hi,

We have a website which is perfectly running fine from last few months(after upgrading to PS 1.7.6.5), all sudden the websites front end stopped working.

We have tried to increase memory limit to 4GB still we get 504 error after long time. we tried to enable debug mode, but we can't see the output in browser as we are getting 504 error.

The server configuration:

Processor: 8core

RAM: 16GB

PHP 7.2

It will be appriciated if I get any help to identify the problem.

Thanks in advance.
