Flutter and Django Integration: SocketException (Errno 111) - Connection Refused Issue

Frontend and Backend Development
1

Using Flutter with Django REST, registration functions in Postman but triggers a SocketException (errno 111) in the app. My test snippet:

Map<String, dynamic> signupDetails = {
  'contact': emailField.text,
  'secret': passwordField.text,
};

try {
  var response = await http.post(signupEndpoint,
    headers: {'Content-Type': 'application/json'},
    body: jsonEncode(signupDetails));
  print(response.body);
} catch (e) {
  print(e.toString());
}

hey, i looked into your issue and sometimes its due to a mismatched host or closed port. have you double checked the server your app is hitting? im curious if your emulat0r settings differ from postman. anyone else encountered this?

hey, maybe u should check if your server is binded to the correct ip addr, sometimes it listens only locally. also, try disabing any firewall tho regarless of port mapping may cause connection refusals.

The issue may also be related to the server configuration and the network settings of your development environment. In my experience, carefully verifying that the correct network interface is in use when running Django can help resolve connection problems. Additionally, ports might be blocked or restricted by system settings, which can cause intermittent failures when transferring data from mobile clients. Debugging network traffic with tools like tcpdump has been beneficial in determining where the connection attempt was rejected.

hey dancingbutterfly, have u double chcked if your django server is properly binding to the external ip? sometimes local proxy settings may interfere. also, verify the http/https mix-up in your endpoints. how does your overall setup look? any other similar hiccups noticed?
