php5-fpm.sock failed (13: Permission denied) error

I recently upgraded some PHP packages on an Cloud VPS server and since that I noticed some errors on the hosted websites. The first thing I noticed was a 502 Gateway timeout error. And after reviewing the logs I found this:

via php5-fpm.sock failed (13: Permission denied) error.

Mise à jour foireuse sur mon serveur avec la dernière upgrade de php-fpm qui m’a planté la communication entre nginx et php fpm. GRRRRRRR !

Merci pour la solution 🙂
