99% of the time the issue is due to the following:
you entered a list of URLs like so:
https://Site.com/products/shoes.htmlhttps://Site.com/products/pants.html
https://Site.com/products/hats.html
however, if you also added a Filter such as :
Include Directory = `/jobs/`
or any other filters.. then that is most likely why the results return nothing or fail.
