AUTH_KEY_UNREGISTERED while trying to GetFile

[lazyjohny500]

While trying to get a channel photo I got an exception AUTH_KEY_UNREGISTERED
from then on all my requests get AUTH_KEY_UNREGISTERED
I tried filePartSize = 1024\1024*32

                    var photo = ((TLChatPhoto)telegramChannel.Photo);
                    var photoLocation = (TLFileLocation)photo.PhotoSmall;

                    TLInputFileLocation inputFileLocation = new TLInputFileLocation()
                    {
                        LocalId = photoLocation.LocalId,
                        Secret = photoLocation.Secret,
                        VolumeId = photoLocation.VolumeId
                    };
                    using (Task<TLFile> uploadFileTask = _connector.Client.GetFile(inputFileLocation, 1024 * 32))
                    {
                            uploadFileTask.Wait(_connector.TimeoutMilliseconds);
                    }

I understand that when I ask to getFile() of channel photo for some channels I got AUTH_KEY_UNREGISTERED.
I temporarily not support the TLChatPhoto.

@knocte I think the issue is according to something that happen in Channels results

Hello,

No, AUTH_KEY_UNREGISTERED is according to Telegram server error, Your current session invalidates by Telegram, it happens when Telegram found that you SPAM somewhere or also in false positive on virtual numbers!

Hi @nimix3
I know it's according to Telegram error.
I'm not SPAMming. I'm using my Telegram account with my private phone (not virtual).
My session is valid, until I ask for getFile() of channel photo.

• If I ask for getFile() of user photo - work correctly.
• If I ask for SearchUserAsync() - work correctly.

Ok, Good luck then

@lazyjohny500 you can try to use Telega. There is an example that downloads a channel photo. I guess TLSharp still does not handle FILE_MIGRATE correctly.

Hi! If you already have file session.dat, this works fo me:
string fullPathToDat = Directory.GetCurrentDirectory() + "\session";
var store = new FileSessionStore();
client = new TelegramClient(apiId, apiHash, store, fullPathToDat);
await client.ConnectAsync(false);
