Angular/http does not working in ionic 3 on device

Ionic Framework ionic-v3
1

Dear All kindly help I am working on ionic 3 project in which currently angular/http does not work or connect to server just response as 404 not found

Nobody will help you if you do not provide more information.

For example, some fragment of the code, the response of the server, the headers involved in the request, etc.

Dear ramon these is no any error just while running the app on device it prints not found server response 404

If it getting a 404, doesn’t that mean the endpoint it not there? Can you connect to the endpoint in your browser?
