Remote server reset the connection

I'm running in to an issue when calculating shipping for packages. See below for the setup. The shipping_service object is just ActiveShipping::USPS.new(login: 'my-login-key')

irb> shipping_packages

This seems to work when I just do 1 package (doesn't matter which one) but it never has worked with 2 packages.

Any thoughts?
