Error with code 406: AUTH_KEY_DUPLICATED

Description and reason:
Telegram technical error

Solution:

You need to remove the selected account from the program and add it again


Detailed description:

The "AUTH_KEY_DUPLICATED" error in Telegram occurs as a result of a technical issue related to the Telegram API. This error is triggered when the authorization key (auth key) used to connect to an account is duplicated. This can happen due to various reasons, such as network failures or technical issues on Telegram’s side. When the key duplication occurs, it disrupts the normal functioning of the automation program, making the account inaccessible for tasks like message broadcasting or managing chats.

The Telegram API strictly controls the uniqueness of authorization keys, so any duplication of the key can result in denial of access to the account. Automation programs that rely heavily on the API might encounter this issue, especially when multiple sessions are running simultaneously or during an authorization failure.

Causes of the "AUTH_KEY_DUPLICATED" error:

1. Duplication of the authorization key (auth key).

2. Technical failures or network issues.

3. Session conflicts within the Telegram API.

4. Incorrect handling of authorization data by the automation program.

Solution for the "AUTH_KEY_DUPLICATED" error:

To resolve this issue, you need to remove the current account from the program and add it again. This will allow the Telegram API to generate a new authorization key for the account, restoring the program's normal functioning. Follow these steps:

1. Open the Telegram automation program.

2. Remove the account that is causing the error.

3. Re-add the account to the program.

Once these steps are completed, Telegram will generate a new authorization key, and the error will be resolved.
