Well, I'd say, diagnosing network-related problems might require some
network-related knowledge. At least I don't know of any dummy's guide on
how to achieve what you want to achieve.

OTOH, maybe the logs of your proxy provide some hints on what is going
wrong. I'd take a look at them - maybe after increasing the log level.
