Is there an example of doing a login system for an angular bootstrap app?

Still getting the same error. is it because I am on the free plan? I thought I can have up to 3 pages, I currently have two and am trying to create the third.

I am trying to add a new page to my angualr app and I keep getting an error:

"something is wrong, the new page isn't created.
the server side is unavailable"
