http: Unhandled Exception: Connection closed before full header was received #41573
Comments

Issue exist on Master and stable. |
|
@Gnpiwano Please provide the info about devices on which you encounter it. Does it happen on both ios and android? does it happen on both emulator and physical device? |

Hi @BondarenkoStas, |
|
I also tried to http.get www.google.nl and that worked fine so it looks likes it has anything to do with this Url. The api is from a well known bank so it should work fine and because natively it does work normally. |

Hi @BondarenkoStas , I am also facing the same issue while fetching data from the server. I am using Swagger Client which frequently throws exception i.e. 'Connection closed before full header was received'. Swagger is using package:http/http.dart [pub.dev> package http: ^0.12.0+2]. |
|
Does anyone fix this issue? What did you do? |
|
@HumbleCarl , |
How ? |

I disagree, I did found a workaround by working around Flutter & Dart! Does not mean the problem is fixed. I call a URL that i can request natively and not through http dart package that crashes in io_client.dart. So I would like to reopen this issue! Thanks in advance! |
|
Another example with public api: It should return response with 403 code, or 204 when provided valid client-certificates.
when called from dart-command-line-app
without any message when called from flutter. |
|
Probably the problem is on the level of SecureSocket:
Nothing is read from the socket. |
|
it worked as expected, After a one-second delay. final response1 = await http.get(...);
...
await Future<void>.delayed(Duration(seconds: 1));
...
// An error occurs when removed the delay.
final response2 = await http.get(...); |
|
The delay didn't help in my case. |
|
Also facing the same issue. Tried to override the active http connections per host as well as using a single client instance across the app ... nothing worked properly. |
|
I think we're seeing the issue on some devices (1/8 test iOS devices), happens on some iPhone 8s, some iPhone 6S, some iPhone 7 (but not all). |
|
Any news about this error? |
|
We are using http library in our network model. And we are facing the same exception in the physical devices in few scenarios. |
|
While I was writing my request code, it started having the 'Connection closed before full header was received' issue, then I realized it happened when I used the jsonEncode from dart:convert library to convert Map<String,String> to String. |
|
I was facing this issue while using the NetworkImage widget and consuming images from a s3 bucket. |
|
hitting the same error on emulators and real devices while debugging. flutter doctor is clean this is the relevant log |
|
@fnicastri Hey, did you find any solution for this? |
Sadly not |
|
I have the same issue. I want to connect a https proxy. If I set the proxy in the chrome extension, it works. If I set via I read the doc https://dart.dev/tools/pub/troubleshoot , but I could not find how can I set |
|
Is there any solution for this? I'm currently facing the same issue and tried everything, but didn't work |

Just adding some more info here. I am running into the same problem with web_socket_channel package. I wrote a small console program to try and isolate it. This code works:
This code does not:
Here is the stack trace from the code that did not work. ws://echo.websocket.org is a test WebSocket echo site on the internet and 192.168.1.16:3000 is a NestJs WebSocket node server (that does work from a web page client using socket.io) running local on my laptop to where this client code was ran. This code was ran straight from the console without any devices or emulators with the command "dart ./websoket.dart". I think you can rule out the emulators, iOS, and Android. Unhandled exception: |

I had faced same issue and tried to build ipa and apk with updated flutter version 1.22.2 and Dart SDK is also updated accordingly. Our app is in testing phase where this issue not occurred yet. It's still under testing. |
