Built ionic app doesn't send requests


#1

Good day.
My application has stopped sending requests and it seems like angular-routing doesn’t work too.
When I use ionic serve everything is fine. My app works correctly.
After running command ionic cordova build browser --no-interactive --prod app successfully built, but works incorrect.
All files in their places, routing set correctl. Seems like the thing in a build.
Any ideas?
