Why does a "Rates Could Not Be Fetched" warning appear for FedEx on Shopify?

This warning typically indicates a problem retrieving FedEx rates for account you are using, so the first step is confirming whether the same shipment can be quoted directly on FedEx's own site. If it fails there too, the issue is account-specific and needs to be resolved with FedEx support directly.

If you want a reliable way to isolate whether a rate issue is coming from FedEx or your Shopify setup, PH Ship, Rate & Track for FedEx surfaces detailed rate-fetch errors so you can quickly tell which side needs attention.
