[eokdev]

This project was working fine some weeks ago. but today it started throwing this error - Error: SocketException: Connection timed out (OS Error: Connection timed out, errno = 110), address = app.myadress, port = 38887

Working fine on emulators
I switched from http to use Dio still getting same error.
Its a hosted api.

Please help!!!

same here

   try {
        result = await wf.currentWeatherByLocation(position.latitude, position.longitude);
      } on SocketException catch (_) {
        
      }

Not able to catch the exception. And when I click forwards from debugger It works and makes the http request successfully!

Internet connection is live and permission is requested

Hi @eokdev. Thanks for filing this. Initially this seemed to me to be related to the http package and I see there is a similar issue being tracked here dart-lang/http#831 but seeing from original comment that this occurs with Dio as well. Can you please provide more information on this, more specifically,

• Can you share a minimal complete reproducible code sample that doesn’t include 3rd party plugins or complex production code (a single main.dart file)?
• Also, does this only occur on Android? I can see a similar issue currently open here Udp packet sending generates error when display is turned off on Android devices #115921

Thank you!

@dam-ease
This issue is occurs on http package and dio package aswell. And Im also following given issues but on those issues people stongly believe issue is related to flutter. I also strongly believe thats related to dart:io-patch

Here is a http request for github

import 'package:http/http.dart' as http;
void main() async {
 

  var url = Uri.https('github.com', '/');
  var response = await http.get(url);
  print('Response status: ${response.statusCode}');

}

Here is Call Stack

_NativeSocket.lookup.<anonymous closure> (dart:io-patch/socket_patch.dart:520)
<asynchronous gap> (Unknown Source:0)
_NativeSocket.staggeredLookup.<anonymous closure>.lookupAddresses.<anonymous closure> (dart:io-patch/socket_patch.dart:0)

Can you please provide more information on this, more specifically,

* Can you share a [minimal complete reproducible code sample](https://stackoverflow.com/help/minimal-reproducible-example) that doesn’t include 3rd party plugins or complex production code (a single main.dart file)?

* Also, does this only occur on Android? I can see a similar issue currently open here [Udp packet sending generates error when display is turned off on Android devices #115921](https://github.com/flutter/flutter/issues/115921)

Thank you!

Yes it occurs on android.

This is my main.dart file

`void main() async {
WidgetsFlutterBinding.ensureInitialized();
await ScreenUtil.ensureScreenSize();

await SystemChrome.setPreferredOrientations([DeviceOrientation.portraitUp]);

runApp(
const ProviderScope(
child: MyApp(),
),
);
}`

but i dont think it has any link to the issue i am having. What do you think?

[dam-ease]

Thanks for your responses @eokdev and @mahirozdin.
I ran the sample provided here and I get a 200 both on Android and iOS. When I turned off the Android device display as well, I got a 200. From the information provided, this seems similar/related to #115921. Can you please check it out?

[mahirozdin]

@dam-ease hey thanks for the tests. Promlem is still occurs even the display is on. And after clicking the continiue button on debugger I can see that data has came already. So data is coming but exception isthrown there is some kind of problem. I wasnt able to solve the issue. When I made a call for google.com there is no problem at all. but for github.com it occurs.

[eokdev]

@dam-ease the error i am facing seems like a network error cuz when i downgrade to a 3g network it works and I do not have the timeout issue. But when I am on 4g network the error happen most times. Using VPN too worked...

Seems like the way the administrator configured the domain or something. Do you have a heads up on this?

[dam-ease]

Thanks for your responses. @eokdev. Can you test with the sample #135495 (comment) to see if this varies with network as well, I still can't reproduce at all on my end.

Without additional information, we are unfortunately not sure how to resolve this issue. We are therefore reluctantly going to close this bug for now.
If you find this problem please file a new issue with the same description, what happens, logs and the output of 'flutter doctor -v'. All system setups can be slightly different so it's always better to open new issues and reference the related ones.
Thanks for your contribution.
