White Screen on my app and error on Bubble dev page

About the last 3 days my app started showing white page, nothing else. I thought it was a temporary issue so I waited. I’ve tried different browsers and cleared cache, but that didn’t work.

Nor can I access my development page in a bubble. I am seeing this error

“Your browser was unable to load some necessary resources, contact your IT network administrator and ask them to allow access to” with cloudfront codes.

I am on Mac 2015 with Sierra OS, maybe that’s an issue. But it was working perfectly fine.

Any advice is appreciated.
