Python has powerful high-level data structures and a simple yet effective approach to object-oriented programming. Python’s command syntax is a huge plus. Its clarity, ease of understanding, and flexible typing make it rapidly an ideal language for scripting and application development in various fields in most areas and all platforms. When you do your task, you receive the following error: RPCError 406: UPDATE_APP_TO_LOGIN (caused by SendCodeRequest) in Python. This is one of the most popular errors that any programmer could make. As a result, why would it appear, but is it resolvable? We’ll go over it with you.

When Does The Error: RPCError 406: UPDATE_APP_TO_LOGIN (caused by SendCodeRequest) in Python Occur?

You are using Telethon in the Python project, but you are getting the following error today, even though it worked fine yesterday.

“telethon.errors.rpcbaseerrors.AuthKeyError: RPCError 406: UPDATE_APP_TO_LOGIN (caused by SendCodeRequest)”.

In another case, you are using the following code.

“from telethon.sync import TelegramClient

...

    client = TelegramClient(phone, api_id, api_hash)

    client.connect()

    if not client.is_user_authorized():

        client.send_code_request(phone)”

You have encountered the error ”RPCError 406: UPDATE_APP_TO_LOGIN (caused by SendCodeRequest) in Python” because the verion of TDLib is out of date, and it must be upgraded to the most recent 1.7.9 version. The cause is that Telegram has converted to 64-Bit identifiers and older versions are incompatible, so it prevents you from loginning with a phone (you can login with QR and an existing account on 1.7.0 version).

The Amazing Approach For The Error ”RPCError 406: UPDATE_APP_TO_LOGIN (caused by SendCodeRequest) in Python”

Surprisingly, you just solved it using the method mentioned below.

The telethon library needs to be updated.

In this case, the telegram has begun requiring the use of 64-bit identifiers for users and chats, but the current stable version of the library does not yet support them. You may encounter the UPDATE APP TO LOGIN error if you attempt to log in.

An asyncio Python 3 MTProto library which allows users or through bots account (bot API alternative) to interact with Telegram’s API is called Telethon.
