I recommend testing to see if this works outside of Target. Try to set up a simple HTML page that redirects to the final destination URL. Here is some sample HTML code I found on how to do that: https://www.rapidtables.com/web/dev/html-redirect.html If the redirect does not work outside of Target it will probably not work inside of Target either.
Hope this helps!
