"USPS Failed to Rate" when rating USPS in SendPro Enterprise
When rating any USPS service with no special services selected, the error message "USPS Failed to Rate" is displayed.
The diagnostics logs will show an additional error of "Invalid URI: The hostname could not be parsed."
If you are trying to ship a regular, non-ERR shipment, select carrier "PB Shipping API - USPS".
Use the USPS carrier for ERR shipments only, with "Certified" and "Electronic Return Receipt" selected.
