TIMEOUTS WHEN PULLING ECS API CALLS

[TAACS]

Am running spec inside a private vpc which is behind a proxy...and running into time out issues.
When I run this inside a public vpc i do not get any time outs

Any suggestion as to why am getting time outs in private vpc, or any idea on how go over issue will be great.
