Our jobs stopped posting to our external career site at random and we have no idea why

We posted a role successfully on January 6 and since than, none of the jobs we have posted are hitting our external career page and in turn, they are not getting posted to other job boards that pick up roles from our external career site. We have no idea why this happened, and how to fix it. We have compared the new job postings to the ones that were successful prior to January 7th and we can't see an issue. Any idea what we should be checking?
