magento2 – Magento 2 table rate works on cart page but not on checkout page

When I check the shipping via table rate for products ordered in the cart page in my magento 2.3.4 site, it comes out fine but on the checkout page, I get the errors in the image below.
table rate not working

I have reviewed the table rates and the configuration , all checks out fine. the cart rules are all fine.

In the checkout page, when I insert the post code and the rest of the address fields, I keep getting the same error for both the FLAT RATE and TABLE RATE.

I need your assistance.
