Why are no shipping methods or rates showing at checkout?

An empty shipping step (“No shipping methods available”) usually comes from a carrier-config error, a broken rate request to a carrier like ShipperHQ or table rates, a country/region restriction on the method, or a cached checkout/index/index layout. We trace the rate request end to end, carrier settings, the quote address, and the network call, and fix the layer that’s actually returning zero rates, then confirm rates render for the regions you sell to.
