URGENT needed - Nginx + FastCGIwrap = 502 error

[Andrew Hutchings]

Hi Kasino,

Two things to check here:

1. are the NGINX workers running as the same user/group as the socket?

2. if this is a RHEL/CentOS/Fedora box (unlikely given the www-data
user): is there anything in the SELinux audit log to indicate that it
blocked this?

Kind Regards
Andrew
