We have the UPS rest carrier setup under Carriers and had ran through testing without any issues. However, when pushing the carrier to the live status with the live ID and secret key, we are encountering an odd error when trying to ship.

This happens after we are on the shipment itself and hit “Confirm Shipment”. We had already gathered the rates via UPS so it does connect just errors on this last step that produces the label and tracking info. Any idea what we are missing?
Thanks,
Adam
