WooCommerce live carrier rates failing: why are real-time shipping quotes missing?
Shipping issues on WooCommerce usually mean rates are missing, shipping classes are wrong, labels fail, or customers cannot complete checkout because no methods appear. Merchants should identify whether the problem is zone configuration, method rules, or an integration failure.
Shipping breaks when zones do not cover the address, methods are misconfigured, class logic conflicts with the cart, or a live carrier integration fails to return quotes. The visible symptom at checkout is often only the last step of a deeper shipping-rule problem.
Check the core shipping troubleshooting guide first, then compare the exact cart, address, and method against your shipping configuration. If the rules look correct but rates still fail, gather logs and continue with support or extension-specific debugging.
