PLEASE NOTE: eBay errors are common. If your item is showing "Failed to List" after attempting to list, you can learn more by clicking on the item receiving error to see what eBay is asking from your listing under 'eBay Status'.
This is a general eBay error and is best diagnosed directly on eBay's portal.
More information can be found as shown in the example below: Make a listing directly on eBay's portal, and eBay should indicate to you exactly what the problem is. If it's not possible to manually create listings on eBay, JoeLister can't automate listings, either.
If you continue to run into this error, file a support ticket for further investigation.
