There may be various reasons for this error. However, one common cause is related to the authorization of your Amazon store. Amazon requires you to re-authorize your store every 12 months. If this re-authorization is not done, it can result in restrictions on your Amazon account.

To resolve this issue, Inventory Ahead provides a simple and easy solution. Follow these steps:

1. Navigate to Settings > Selling Channels.
2. Locate your Amazon store.
3. Click on the three dots on the right-hand side of your store.
4. Select “Edit” > “Re-Authorize Store” and follow the prompts provided.

If the error persists and it is not related to the store authorization, please contact our support team at Support@InventoryAhead.com. One of our agents will be available to review the matter and assist you further.
