Connection error cannot send requests while disconnected telethon

Hi
I have problem with this kind of implementing telethon and can’t find out why ?!

...
def create_telethon_session(self):
    target_phone = self.phones[self.phone_index]
    with TelegramClient(target_phone + "-x", self.api_id, self.api_hash) as client:
        client.connect()
        if not client.is_user_authorized():
            client.send_code_request(target_phone)
            client.sign_in(target_phone, input("Enter the code: "))
        
        logging.info(f">> create_telethon_session client : {client}")
        return client


def delete_messages(self):
    target_group = "@XXX"

    # client = self.create_telethon_session()
    logging.info(f">> delete_messages client: {client}")

    while True:
        logging.info(">> get 1000 messages for deleting ...")
        messages=client.get_messages(target_group, limit=1000)
        logging.info(f">> messages.total: {messages.total}")
        if messages.total > 1:
            logging.info(">> deleting ...")
            for i in messages:
                # logging.info(f">> {i.id} deleted .")
                client.delete_messages(target_group, i.id)
        elif messages.total <= 1:
            break
...

getting this error :

«Cannot send requests while disconnected» error when trying to download all media from Channel #958

I try to write code to download all messages and media from specific channel. Getting messages without downloading media works fine. But with file download it is failed usually earlier than on 10 iteration. I use Python 3.6, Telethon 1.2.

The text was updated successfully, but these errors were encountered:

Could you enable logging.INFO and tell me if there are «Exporting authorization for data center» messages?

This log is for successful execution of «client.download_media(message, file=’download/’)»:

This log is for failed execution of «client.download_media(message, file=’download/’)»:

INFO:Received response without parent request

That is #658 once again, in this case File(type=FileJpeg(), mtime=1534442352, bytes=b») .

Anyway, back to your issue, it’s clear to see that in the first case the first attempt works, while in the second case, it fails (yet connects in the second attempt).

I fail to understand how your log connects and disconnects when the code flow doesn’t go like that.

Seems to have fixed it.

I’m experiencing the same issue under similar circumstances: «Cannot send requests while disconnected» when mass-downloading media from channels.

Also, I’m sometimes seeing this error (not sure if they are connected, but still):

No idea how I’m going to debug though.

Also this sequence of events seems to happen quite often:

utils.getFile is my app method, its job is to ether call client.download_file , or get channel post ( channels.GetMessagesRequest ), extract file_reference and then call client.download_file .

same here on version 1.16.2
any way to fix it?

is sync run account, and banned. but sync is connect. not disconnect

Could you post the full traceback with the error under the latest version ( pip3 install -U https://github.com/LonamiWebs/Telethon/archive/master.zip —user )? Having a traceback where the lines match with the code is very valuable and would help me introduce bogus errors to see if I can get the same behaviour.

@dmitrdv with Telethon==1.19.5 everything works well
try code bellow:

instead define/connect client outside def and call def.

Closing as this was reported a fairly long time ago and the cause is probably some connection issue.

[QST] How to cek client status, connect or disconnect. #3763

I make a bot with bunch of order. few weeks ago success, but yesterday my script not work anymore. error in connect and disconnect status.

previously I do this:

previously, it’s works.

but then today. suddenly error database is locked (means telethon client status is still connect).

ok, I read the documentation and from other source to close connection after get some data.

still not works, client still connect, and the database is locked.

OK, now I try to different approach. I try to make client always connect. I make like this:

but then, a few minutes later error. «cannot Send requests while disconnected».

Is there a way to know the connection status of the client, so if we still connected, I by pass the script to make a connection order to avoid database locked error.

while it disconnected, I can told the script to make a connection first before getting data to avoid error (cannot Send requests while disconnected).

now I try do this, set client in global, and try to call client.connect every time want get data.

client = TelegramClient(session_path,api_id,api_hash,
device_model=model,
system_version=sys_ver,
app_version=app_ver)

but I not satisfied because it make my bot so slow in responding

Telethon ConnectionError

Hi. I am testing a small script that works with telegram api through python module ‘Telethon’. Here is the code:

When i launch it on my PC it works correct, but when i try to run it on the Pythonanywhere server it fails with an error:

I got this error before, and then i found this article: http://help.pythonanywhere.com/pages/403ForbiddenError/ so I connected through proxy, but nothing changed. It is strange because I found this in the whitelist:

Hope you will help me to solve this problem. Thank you.

Are you sure that you are actually running the code that configures the connection to use the proxy?

As described here https://docs.telethon.dev/en/latest/modules/client.html#telethon-client If «connection» is not MTProxy, proxy argument for TelegramClient» meant to store function parameters for PySocks, like (type, ‘hostname’, port). And as also described there, by defaullt connection is «telethon.network.connection.tcpfull.ConnectionTcpFull.». Correct me if I am wrong.

P.S. I have just checked the same code from my PC using free http proxy from the internet. It connected.

I see that MTProtoSender can use a number of different transports. Make sure that it is using the HTTP transport and not one of the others.

Sadly, but I can not make it work with HTTP connection even from my local pc. I did not know that free accounts supports only HTTP connection, it was not mention on help page. Thank you for response.

by the way, perhaps try to follow some of the instructions from here to make it work from your local pc?

Thank you for reply, but this is instruction about how to create telegram bot using teletop, and i want to create telegram client with telethon.

In that case, you’ll have to rely on the telethon documentation to get it working.

you should use something like python-telegram-bot, pytelegrambotapi etc which uses http api. telethon uses mtProto over tcp which might not be supported through pythonanywhere

Yeah i understand, but the problem is, that i want to create a little script, that will act as a user, not bot. Anyway thank you for reply, if I find the solution, i will share it here.

hi! Maxu360, what about your question? did you find solution? i have a problem like this..

hi! vikadashyan , Maxu360 , did you find out how to solve the problem with telethon ?

Update 2020-01-12 For some reason Telegram has stopped accepting wildcard HTTPS certificates for bots, so unfortunately this tutorial will no longer work on a PythonAnywhere free account. For the webhooks part of the tutorial to work, you will have to get a paying account with a custom domain. Thanks to fivechar for letting us know in the comments.

so it seems, there is no free way.

That only applies if you’re using a webhook-based system for your bot — if it’s a script that connects outwards to Telegram, and runs in a console, then it should still work.

One caveat: consoles do get reset from time to time as part of system maintenance, so your bot would stop working when that happened and you would have to restart it. Paid accounts can set up bots as always-on tasks, which would allow you to avoid that.

thx for caveat, but I cant even connect to telegramm api. neither through ‘proxy.server:3128 nor my proxy

Which library are you using?

[edit: I see you’ve posted on another forum thread, so I’ll pick it up there]

as signed it tilte of topic — I am trying to set up Telethon library. thx for help

why doesn’t the code come from telethon telegrams on your hosting?

ConnectionError: Not connected #1187

api_id = 123456
api_hash = ‘xxxxxxxxxxxxxxxx’

with TelegramClient(‘testApp’, api_id, api_hash) as client:
client.send_message(‘me’, ‘Hello, myself!’)

The text was updated successfully, but these errors were encountered:

how do i solve this problem?

Please enable logging as explained in the documentation and show the output with that code.

can I continue this conversation?
so my code mostly took from documentation:

`import logging
from decouple import config
from telethon.sync import TelegramClient

api_id = config(‘APP_API_ID’, cast=int)
api_hash = config(‘APP_API_HASH’)
logging.basicConfig(level=logging.DEBUG)

with TelegramClient(‘anon’, api_id, api_hash) as client:
# Getting information about yourself
me = client.get_me()`

and this is the output:

is it authentication problem?

@Lonami hello, could you please comment?
should I open a new issue?

Does it happen consistently? Is your country limited?

This is the only result I get
By limited you mean Telegram blocking by state? No, it is available in my country

What version are you using?

It is strange, because it’s working for me and probably everyone else or there would be more reports. Telegram shouldn’t be closing the connection so early and I don’t know if reconnecting will help.

I just tried to put this code to DO VPS and it’s worked

So problem in my Mac, please advice what should I check?

The log says INFO:telethon.network.connection.connection:The server closed the connection , but it doesn’t say when it happened (i.e. has it sent/received any data at all before this happened?) which would be helpful to know, so if you’re willing to investigate that (maybe add a breakpoint on that log line so you can inspect the stack back up), it would be nice.

So it is happened on one of iteration at base_events.py, line 539.
I am really happy to help, but I’m not sure what to do — I’m quite new at programming

asyncio way of dealing with sockets probably won’t make debugging this easier, due to how it works. It may not be a suitable task for a new comer like you, and that’s fine.

OK, so if I can help you somehow — just let me know

Closing due to inactivity. Might be related to the more recent #1376 so discussion should probably happen there.

Hi. I am testing a small script that works with telegram api through python module ‘Telethon’. Here is the code:

from telethon import TelegramClient, events, sync

    if os.environ.get('PYTHONANYWHERE_DOMAIN'):
        pythonanywhere_proxy = (socks.HTTP, 'proxy.server', 3128)
        print('Connecting through proxy')
        telegram_client = TelegramClient('testing_session', TELEGRAM_API_ID, TELEGRAM_API_HASH,

ConnectionError: Connection to Telegram failed 5 time(s)

I got this error before, and then i found this article: http://help.pythonanywhere.com/pages/403ForbiddenError/ so I connected through proxy, but nothing changed. It is strange because I found this in the whitelist:

...
api.telegram.org
...
core.telegram.org
...

Hope you will help me to solve this problem.
Thank you.
