@mclarendan and @rcwatson Thanks so much for getting in touch! So, embarrassingly this was a case where I didn’t have control over managing my DNS. A client of mine was using a separate company to manage it and it turns out it was a DNS issue.
Unfortunately, they didn’t give me much information on what, exactly, was wrong. They might have been a little embarrassed too haha. But maybe that’s a good place to start if you’re having similar issues?
We’ve got everything up and running properly now.
