App is not loading

Hello, I am developing an app. It was working fine last night. Today I am trying to load it and I am not able to see anything just a blank screen. Any help is appreciated.

Is there any error did you got …
or else do once again generate app to build and let me check …

The page isn’t loading for me either. I have used it once before around three months ago but now pages do not load. I have tried different computers, mobile devices. Same result. See image for errors.
