Hi Maxim,

We implemented to module and still had some trouble. A lot of the
connections would return " 503 Service Temporarily Unavailable". Our
configuration works fine without the load balancer but then gives these 503
errors behind the load balancer.

Looking into the error logs I notice a lot of these errors both with and
without the load balancer "connect() failed (111: Connection refused) while
connecting to upstream". Could this be the reason that we are having
issues?

Thanks!
Rami
