_ClientSocketException: Failed host lookup

[Wizzel1]

Describe the bug I am getting regular

_ClientSocketException
Failed host lookup: 'rhfwwqrwdplqqjxcprww.supabase.co' on my Windows app. 

Any idea why this happens?

???   ????????? supabase 1.9.5
???   ???   ????????? functions_client 1.3.2
???   ???   ????????? gotrue 1.9.0
???   ???   ????????? postgrest 1.3.2       
???   ???   ????????? realtime_client 1.1.1 
???   ???   ????????? storage_client 1.5.1

It simply means you don't have an internet connection. I suggest you to do quick google searches before creating an issue. This shows something liks this

[Wizzel1]

If I hadn't done a Google search I wouldn't have created an issue. I have found your linked issue as well but since I am on windows, I don't need to set any permissions

[Vinzent03]

Can you do other https requests in your flutter app? Or is the issue specific to the supabase client or server?

Apparently this only happens when I try to upload multiple images at the same time to a storage bucket:

final futures = imageDataList.map((imageData) async {
   return Supabase.instance.client.storage
          .from('my-images')
          .uploadBinary(
            'my/imagepath/image.png',
            imageData,
            fileOptions: const FileOptions(contentType: 'image/png'),
        );
});
await Future.wait(futures);

When I run a for loop it works every time:

for (final imageData in imageDataList) {
    await Supabase.instance.client.storage
        .from('my-images')
        .uploadBinary(
          'my/imagepath/image.png',
          imageData,
          fileOptions: const FileOptions(contentType: 'image/png'),
    );
}

I don't have a mac device, but I can't reproduce your issue with an online supabase project in the client tests:

final bucketName = 'with-limit-${DateTime.now()}';
await storage.createBucket(bucketName);
final list = List.generate(50, (index) => index);

final futures = list.map((e) => storage.from(bucketName).uploadBinary(
    "$e", file.readAsBytesSync(),
    fileOptions: FileOptions(contentType: 'image/png')));

await Future.wait(futures);

@Vinzent03 Okay thanks for verifying, I will keep an eye out for this error.

Couldn't reproduce it so I closed this for now

Hello, I'm getting the same error Failed host lookup: 'mydbname.supabase.co' error all at once. Do you know what it could be? I have an internet connection and have tried different networks. Thanks

@meulencv On which platform? Can you query other websites via http package?

[meulencv]

Hello, Right now I get the error on android, it seems to me that on web the error is not shown. Yes, the internet works, in fact, the app loads .json files and photos from the internet. Also, if I disable the errors breakpoints in the debug, the app works correctly.

I am also getting this error all of a sudden after upgrading Flutter to version 3.13.0 I have tried on both emulators and real devices. If you push through the exception, it still fetches the results from the database without any issues. I have logged a ticket here but happy to close that if this one is to be reopened. https://github.com/supabase/supabase-flutter/issues/595

[meulencv]

I got the error in the same version, I think it's related as you said.

I also get this same error, this mine happens when authenticating a client... it happens on windows, if I push through the exception everything works fine.

[thefredo1000]

I do get the same error, I'm on Mac running an app on Android, any updates on this?

[dshukertjr]

The cause is most likely not Supabase. Check that you have given internet permission on your app and see if your app can make HTTP requests to other servers.

Anybody still has error? I got exception after some request to supabase 🤷‍♂️
