Provide issue context below using code examples, images, or links
When calling Postmate with Slow 3G/Fast 3G internet connection, the connection might not be established on time. The maximum time Postmate allows is 500ms * 5attempts which is 2.5 seconds. For slower connections it might not suffice. Rejecting the promise allows the user to use some sort of handling logic.
