Redirection URL works fine directly but not via E-junkie's links

« Return to Redirection after payment

The problem may be that when we redirect to your URL, we append some order details to the end of that URL; these details would normally be ignored if the landing page isn't specifically looking for them, but the server at your particular landing URL may be getting tripped up by that somehow.

One solution you might try is using a link-shortener like TinyURL.com or Bit.ly, etc. to get a short link which forwards to your intended landing page, and then use that short link as your product's Redirection URL.
