I did setup a Web Tools account, got the username, password and gateway URL from USPS. They also activated the Production Servers and according to them I am all good to go and it should be working fine. But it is not. I add a simple product that weighs only 4lbs so way under their 70lbs limit. I’m allowing all countries (for this example shipping to Los Angeles, California), and tried with only 1 USPS method or all, neither option worked.
