500 response?

Normally timeouts results in 504, and if you see 500 this might 
indicate that in fact request failed not due to a timeout, but 
e.g. due too loop detected.  This in turn might mean that there 
were more than one request to the server X which failed.

Try looking into error_log to see what's going on.
