Why the order cannot be delivered to my domestic market?

[mustard-seed]

Good day experts.

I have set up the shop, only realizing the checkout page has problem. I have already set up the shipping rates and also domestic + international market. But when I try to check out with a domestic market address (in my case, Hong Kong), an error message shows up that says the order cannot be delivered there. 

Can someone help please? Thank you much in advance.

I have figured out the problem. I have set up 2 warehouse, say A and B, and while I set up warehouse B as default, it does not use my shipping rate for warehouse B. So I copy the shipping rate for warehouse B to also warehouse A, and now checkout is possible. Hope it would be helpful to other Shopify sellers.
