5 years ago I get this error very very intermittently on my environment.
I have wifi Windows 10 PC running GraphQL NodeJS Express server on 192.168.1.5, trying to do http (not https) requests on http://192.168.1.5. I have a Genymotion Android phone running.
This error occurred repeatedly for one particular query type. But I somehow fixed it by changing the code to wait for response or something like that.

5 years ago I remember the issue occured on Genymotion (android emulator) on the same computer I was using intellij.
I ran flutter in debug mode via intellij and that's where I saw the error.
I think I fixed it by doing an await on the Future function which did the call.

5 years ago If you are making connection requests inside a future which you should, make sure its an asynchronous task with await properly used. Also as a side note for images, use a placeholder just in case your app misses to fetch from network

5 years ago I'm getting this error frequently as well.
I/flutter (15859): Another exception was thrown: HttpException: Connection closed before full header was received, uri = https://static.checkiday.com/img/600/doctor-563428.jpgCould this be related to this known bug? https://github.com/dart-lang/sdk/issues/21798

5 years ago Some context to my use case:
I am going to display multiple images in a list, so I precache them:
for (Event event in _events) {
precacheImage(NetworkImage(event.image), context);
}Then I use the image that was preloaded:
FadeInImage(
placeholder: const AssetImage('assets/placeholder.jpg'),
image: NetworkImage(event.image),
fit: BoxFit.cover,
width: double.infinity,
height: 256,
),@westy92 you probably need to do same rate limit to avoid too many concurrent requests.

I recently changed some code to wrap my image with a DecorationImage, I wonder if this might fix your problem?
westy92
commented
5 years ago I switched from using precacheImage() to using cacheExtent and am seeing the error less, which makes me think it is indeed due to too many concurrent connections.
I'd like to rate-limit NetworkImage, but can't find a way to do so.
If I had access to the underlying HttpClient, I'm guessing I could set maxConnectionsPerHost.
westy92
commented
5 years ago I figured out how to limit the connections on the underlying HttpClient of NetworkImage!
I globally overrode the HttpClient: (ref: https://github.com/flutter/flutter/issues/19588)
class MyHttpOverrides extends HttpOverrides {
@override
HttpClient createHttpClient(SecurityContext context) {
return super.createHttpClient(context)
..maxConnectionsPerHost = 5;
}
}
void main() {
HttpOverrides.global = MyHttpOverrides();
runApp(MyApp());
}Hopefully this fixes my issue. Thanks for the connections tip!

5 years ago Hi,
I need to display a list of products and each product has an image and some details. I'm using silverlist for this purpose. I'm frequently getting " Another exception was thrown: HttpException: Connection closed before full header was received, uri = https://zoomtail-processed-images.s3.ap-south-1.amazonaws.com/raw-images/raw-W0104-005493_1.webp" this error and the above solution of overriding the global httpclient doesn't help for me.
I've tried to pre cache the network image and also tried using cacheextent, but to no avail. Could you help me with this?
Thanks.

(repost from #21798)
We are building a companion application to our web-based CRM. One of the features is sms/mms. Because the information might be private, we are serving the images behind an authenticated API that redirects (302) to an S3 short term URL (5 minutes).
Anecdotally, I can say NetworkImage seems fine on conversations that only have a few images (like 2 or 3). On a conversation thread that I am using that has 9 images, frequently one or two of them will have this issue immediately. (I will get the error Connection closed before full header was received, uri = ... in the "debug console" and those images will not load.
(A coworker pointed out that if you copy the address from the error in the debug console and paste it in a browser, it loads and is valid.)
It's going to be very embarassing if randomly, sometimes, some of the images won't show up. :-(

5 years ago I finally stumbled on a StackOverflow that mentioned fixing this with cached_network_image package. I tried it out and it did fix the issue. It also had the added benefit of making the screens faster on subsequent views (because images are cached locally now).
So, although the issue still remains for others, I'm happy that I was forced to find CachedNetworkImage().
It was a very easy drop-in replacement for NetworkImage, here are the two places I had to change (the second being only a tiny bit more complex).
// BEFORE:
child: ClipRRect(
borderRadius: borderRadius,
child: Image.network(imageUrl),
),
// AFTER:
child: ClipRRect(
borderRadius: borderRadius,
child: CachedNetworkImage(
imageUrl: imageUrl,
errorWidget: (context, url, error) => Icon(Icons.error),
),
// BEFORE:
Expanded(
child: PhotoView(
imageProvider: NetworkImage(images[currentIndex].imageUrl),
),
),
// AFTER
Expanded(
child: CachedNetworkImage(
imageUrl: images[currentIndex].imageUrl,
imageBuilder: (context, imageProvider) =>
PhotoView(imageProvider: imageProvider),
),
),

4 years ago @cfchris CachedNetworkImage was good to know but unfortunately, that doesn't solve the original issue here. I have same use case as yours and CachedNetworkImage just reduces the frequency but does not resolve completely. Did you experience the issue again?

On my side converting urls on AWS to http didn't do the trick, I had to use that lib instead "optimized_cached_image" and it works as expected

Thank you for the fix! However, It is really sad that I cannot use an HTTPS connection for images in Flutter. I hope this gets fixed soon.
FYI I am using S3 bucket images and 5 out of 50 are failing with Connection closed before full header was received.
I am also using cached_network_image to render the images.

What i meant by that is literally changing the request from https://mys3bucket.amazonaws.com to http://mys3bucket.amazonaws.com. I could only do that becouse the s3 bucket i am using allows me to work with http or https requests.
For those using the package cached_network_image, i made a gist with my solution https://gist.github.com/gabcarneiro/02580611279c85179db015ad2c7ed936

Could be a workaround but far from ideal. HTTPS request is such a basic feature of any platform yet the flutter one is so buggy.

3 years ago In my case (error "HttpException: Connection closed before full header was received") the call was to an https address using Microsoft Internet Information Services as backend, in the SSL settings of the website in IIS i had mistakenly set "Client certificates: Accept" instead of "Client certificates: Ignore", setting "Ignore" solved the problem.

Network image throwing this exception on a random image. I have a list of image thumbnails, when clicked on any, the full size image is fetched using Image.network. Suppose i have 10 images and the exception was caught on clicking the 5th image. On running the app again the exception will be on a different image say 8th one.
