I finally got Nginx working with LDAP and it's been running for several days, then I rebooted the system and could no longer connect to any sites. I was getting 502 and 404 errors, even though I can do a netstat -plunt and see that nginx is listening on the IPs.
I did a restore of all the domains and the sites are up and running again, but after a reboot, I get the same issue. The sites no longer respond until I do a restore.
What would be causing this and any clues on how to fix this?
