Getting 500 Error when trying to access Rails application through Apache2

Question

Hey,

I'm using Apache2 as proxy and mongrel_cluster as server for my Rails applications. When I try to access it by typing in the url I get a 500 "Internal Server Error" but when try to locally access the website with "lynx http://localhost:8200" it works.

This is my config:

<Proxy balancer://sportfreundewitold_cluster>
BalancerMember http://127.0.0.1:8200
BalancerMember http://127.0.0.1:8201
</Proxy>

Does anyone know what could be wrong with it?
