Cannot resolve the timeout issues (504 errors).

I've tried changing the apache timeout. It only affects the front end of the website, not the back end (unless I am searching for something).

I've got this happening on two sites, two fresh CWP installs on new fresh Linode instances.

I am running Apache with PHP 8.0.x as the FPM set version. The memory limit, execution timeout etc are all very high, so I don't believe its that.

I've looked at https://stackoverflow.com/questions/33375823/apache-proxfy-fcgi-error-dispatching-request-to but anything like changing the http.conf file and the timeout just breaks apache!

Any help would be great.

Look at tuning options available in the PHP FPM user config file for that account:

/opt/alt/php-fpm80/usr/etc/php-fpm.d/users/user.conf
I'm using nginx instead of Apache, but I did have to apply some Fast CGI buffer tuning in its configuration when I was seeing some timeouts:
