Please, describe the problem here and provide additional information below (if applicable) …

I Just set up Apache and Passanger, but instead of reaching the frontend I always get “Incomplete response received from application”. I really dont know what is wrong. I followed the instal guide step by step… Does someone got any ideas where to look or knows how to fix the issue (or even what could be missconfigured?) Thanks in advance!
Versions of the related components and OS (frontend, hypervisors, VMs): 6.8.3

**Steps to reproduce: instal Apache and Passanger **

Current results: Trying to access Frontend trough Browser always returns Incomplete response received from application

Expected results: get sunstone frontend

Solved memcached was not installed…
