I have a simple deployment with some webservers connected to an AWS ELB. This ELB in-turn has some application servers behind it.
The webservers are unable to connect to the application server ELB. The httpd error log is full of:
[Thu Dec 22 15:28:05.897273 2016] [proxy:error] [pid 10188] (70007)The timeout specified has expired: AH00957: HTTP: attempt to connect to 54.254.179.37:80 (elblinkhere) failed

I have tried to check if this is an SELinux issue but that does not seem so.
I have also read a large number of threads on the internet about this and not come across any solutions.
My question(s):
1. What other methods can I use to resolve this?
2. How do I resolve this?
Did you configure your ELB as external and also enabled necessary port for ELB's security group?
