PHP-FPM Socket File permissions

Hi, I'm having issues with the permissions on the socket file when fpm is enabled and suphp is set as php handler. It created the file as 644, but getting permission denied messages. If I manually change to 664 it works as expected. Where abouts is this controlled? I've tried setting umask = 117 in /etc/suphp.conf I think it's related to the suphp handler setup, but on a machine running 7.2.30 it is working as expected, but it also a newer build. Cpanel 88.0.5 PHP 7.2.31 (cli) (built: May 25 2020 10:15:56) ( NTS ) Cheers Steve
