Issues Importing Excel Product list - Nopcommerce 4.0

Hi there - I'm receiving a 404 when attempting to import a product list generated in Excel. This even happens when I export the product list and immediately import the generated xlsx file so I'm inclined to think it's unlikely to be a file format issue.

Error message (after selecting the xlsx to be imported):


This xxxxxxxxxxxxxxxxxxxxx page can’t be found
No web page was found for the web address: https://xxxxxxxxx/Admin/Product/ImportExcel
HTTP ERROR 404

Hello Lumbin,

Can you please share error log?

Thank you,

Any ideas?

I don't think that error is related to the import.
