Link to external url not working in a repeater

Edit: Solved. Just had to link in frame > parent frame instead of open link.

Hi, my prototype has an article repeater which consists of many news articles. I have followed the following tutorial (linked below) to link the “read button” to an external website, i.e. on click of the read button, directs me to the external website. Each read button is linked to its own relevant article on the external website. However, when I preview to click it, the error shown is that the website refuses to connect.
Am I doing something wrong or is it because of the website I am using? The websites are open to public and don’t require any login to view.
