External page not loading

Hi, Within my business's website, I want to direct a link to a Constant Contact page with archived employee newsletters. I found the place to paste the url. From the sitefinity admin page, it looks as if I have published it properly. But when you click the link from the live site, the page doesn't load. No error message, it just has a spinning wheel that never stops. Any ideas?

The response to "clicking on a link of the live site" is managed by the browser and your computer/network, not Sitefinity - which is long out of the game by the time everything is rendered. I guess the obvious is to check the URL of the link at the browser and make sure it's what you expected, and if correct, try it directly from the addressbox of the browser.
