Is nginx running as user nginx by chance? Check /etc/group for clientXY entries, they're typically assigned to www-data. If nginx runs as "nginx" there's no way it is allowed to read from that socket. Either run nginx as user www-data ( nginx.conf user www-data; ) or ... don't do this: change sockets chmod to 666 which would basically allow everything to read/write that socket and is a bad idea. Edit: you could also try adding nginx to www-data group $usermod -a -G www-data nginx
