Error: connect ETIMEDOUT

Hi - trying to deploy this to my aws account; have everything setup on the AWS side and I am behind a corporate proxy; but I have set my HTTP-PROXY & HTTPS-PROXY env vars in my shell and can run the aws cli w/ out a problem, yet still receiving this error...any suggestions to get around this? thanks.

LIBP45P-16600WL:.aws n0224265$ llama deploy -r $LAMBDA_ROLE_ARN

Something went wrong:

Start with the `llama deploy -r $LAMBDA_ROLE_ARN` entry point and trace how it connects to `lambda.us-east-1.amazonaws.com` when HTTP-PROXY and HTTPS-PROXY are set. Reproduce the timeout if possible and determine whether deployment succeeds through the corporate proxy or needs a documented configuration change.
