“Shipping: Not Available” – When it should work

Hello.

Shortly explained, the latest 3 orders it say “Shipping: Not available” When there is possible shipping methods to the country. I have to order it manually with chrome extension but it’s really frustrating. Maybe is this because it is not the same shipping provider or speed? But this have not happened to me previously and on previous product I have been selling from another seller.

Would be awesome if you could check this for me.
Thanks.
