php-fpm Socket File Permissions

Having problems trying to enable php-fpm. Get the following error: AH01079: failed to make connection to backend: httpd-UDS Found that the socket file is created as permissions 640. If I change the 660 it works fine. Is this the correct change? How do I change the default permissions? Cheers Steve cpanel 88.0.5 Apache/2.4.43 ea-php72 7.2.31
