Blank White Screen but source html is there

I’m using a GitHub repository to build in a simple html page in the pages tab. The dev site works fine:

However, I’ve also added a custom domain to that same page and while the html is there if I view source html, the page displays as blank (white) in all browsers.

Any thoughts for troubleshooting?

I’ll answer my own question. It turns out that I also had a cloudflare app installed that wasn’t authenticating properly. When I deleted the app, the site is now working!
