Although everything seems correct, let's double-check this. What's the
output of following commands?

# (stop, then start php-fpm)
# date +%Y-%m-%d\ %H:%M:%S
# ls -ald /var /var/run /var/run/php-fpm.sock
# getfacl /var/run/php-fpm.sock
# groups nginx
# groups www-data
# ps aux | grep -F -e php -e nginx

I bet it's just a small detail you've missed.
