Just adding here that the listen.acl_users directive should be commented, otherwise, it will override the listen.owner and listen.group values:

; Set permissions for unix socket, if one is used. In Linux, read/write
; permissions must be set in order to allow connections from a web server.
; Default Values: user and group are set as the running user
;                 mode is set to 0660
listen.owner = www-data
listen.group = www-data
listen.mode = 0660

; When POSIX Access Control Lists are supported you can set them using
; these options, value is a comma separated list of user/group names.
; When set, listen.owner and listen.group are ignored
;listen.acl_users = apache,nginx
