Hi! This past Tuesday (4/15) around noon customers stopped being able to checkout on our website. After they enter in their address, an error message pops up saying ‘Your order cannot be shipped to the selected address. Review your address to ensure its correct and try again, or select a different address’. We have reached out to shopify but have not gotten any resolution. We have had multiple people check out back end, and look over our shipping profiles and no one has found anything out of the ordinary. What is so weird is that we have not changed any settings at all, it just randomly started being an issue. It is also affecting our shipstation account, and we can not currently print any labels. Has this happened to anyone else? Any advice at all will be helpful!

Hi @SGP1910

If everything in your shipping profiles are checked out, I highly suggest to check the inventory location where your products are set to and check the shipping location of your shipping rates if it is under that inventory location. I highly suggest that you remove custom shipping profile if you have any as well.
