After an update of my system I ran into a bad gateway error of my PHP apps running on Nginx.
1 connect() to unix:/var/run/php-fcgi-vhostname-php-fcgi-
everybody! That's my issue too. I just changed my fpm user to vagrant, restart my pools and ... it's done! Here comes my conf:
user = vagrant group = nginx listen.owner = vagrant listen.group = nginx listen.mode = 0660
Hope it can help someone.
