Exporting wordpress posts to website

Up until a couple of weeks ago, we had an RSS feed on our website (not wordpress) of the most recent posts from our wordpress blog (of a different URL). About two weeks ago, it stopped working and myself and my coworker were unable to figure out why. I was looking for other ways to export this information to our website, but I was unable to find the answer…most of the solutions appear static, whereas the prior usage was continually updating. Can someone point me in the right direction?
