Recently, an update and a reboot of CWP on Rocky 8, i encountered 502 Bad Gateway error on CWP User end services (Like mail, roundcube and user panel).
I started searching on internet for what could be the reason, for 2 hours i went through many forums, threads, complicated configuration posts.
Turns out it maybe a simple fix. When I checked a few things and one specific helpful posts at bobcares.com, it turned out to be a really simple fix.
So, open SSH terminal with root and check if the following service is running or not!
systemctl status cwp-phpfpm
If its not running or active, then run the following command:
systemctl start cwp-phpfpm
