php - 504 Gateway Time-out issue -

I am trying to run a PHP script and it runs for about 60 seconds or so, and then this page is Which says that a 504 Gateway is a time-out.

I am faced with this problem all day and I have implemented many things that I have found around the Internet, but it still does not work. These include editing the FCGID.com file, editing HTAC, and even entering the Plesk panel, and editing the settings in it.

For testing purposes, I am giving 2G and 600 seconds to run it, which should have enough space and time. But it does not work at all.

I have read online that this can happen with NGNX, and it says "NGNX" on my error page, but to be honest I have not really been told about this.

Any help would be appreciated.

Thanks
