aiohttp.client_exceptions.ClientConnectorError when try to connect host api.telegram.org

[MykolaBordakov]

Describe the bug

Good day. I try to use aiohttp for sending messages bey telegram bot directly thru telegram API. I test my code on local machine it is works fast and fine. But, when start do it from docker container my code starts to have an error :

aiohttp.client_exceptions.ClientConnectorError: Cannot connect to host api.telegram.org:443 ssl:default [Connect call failed ('149.154.167.220', 443)]

But, that error i does not have all the time. Container can work well, after some time passing it starts to catch errors. My functions code : async def send_msg_asy(text : str,token : str = BOT_TOKEN, chat_id : int = GROUPE_CHAT_ID): async with limit: async with aiohttp.ClientSession() as session: url_req = 'https://api.telegram.org/bot{}/sendMessage'.format(token) data={'chat_id': chat_id, 'text': text} async with session.post(url_req, data= data) as resp: req = await resp.json() if limit.locked(): logging.warning("Concurrency limit reached, waiting ...") await asyncio.sleep(2) if not req['ok']: logging.error('Massage not sent. Error code: "{}".Description: "{}".'.format(req['error_code'], req['description'])) logging.info("Massage was send!") await session.close() Function running by such code :await send_msg_asy(text = text)` My Dockerfile:

`FROM python:3.9.13

WORKDIR /code

COPY ./requirements.txt /code/requirements.txt

# RUN apt-get update RUN pip install --upgrade pip RUN pip install --no-cache-dir --upgrade -r /code/requirements.txt RUN pip3 install pyOpenSSL

COPY ./configs /code/configs RUN mkdir -p /code/logs COPY ./main.py /code COPY ./costum_logging.py /code COPY ./db.py /code COPY ./functions.py /code COPY ./models.py /code COPY ./schemas.py /code COPY ./topik_algo.py /code CMD [ "python", "./main.py"]`

To Reproduce

I`m use explained above function in pare of confluent kafka consumer.

1. Fist run consumer server.
2. Send some txt massage to telgram..
3. After some time you will have an error during sending massages to Telegram.

Expected behavior

This just looks like a networking issue. Maybe there is a problem with your docker container, or ratelimiting from Telegram? Maybe try running curl or similar inside the docker container when you see the issue, and see if you can reproduce the connection problem outside of the Python program.

This doesn't look like an aiohttp issue.

File "/code/costum_logging.py", line 24, in emit while frame.f_code.co_filename == logging.file: AttributeError: 'NoneType' object has no attribute 'f_code'

That looks like a bug in your code...

Thank for reply. So, this one "AttributeError: 'NoneType' object has no attribute 'f_code'" i have becose script on saht down try to close session for cassandra DB. I will fix it.. Also, i found some solution in internet about it. And update my function. Now it is testing now. Here my updates : async def send_msg_asy(text : str,token : str = BOT_TOKEN, chat_id : int = GROUPE_CHAT_ID): async with limit: async with aiohttp.ClientSession(trust_env= True) as http_session: url_req = 'https://api.telegram.org/bot{}/sendMessage'.format(token) data={'chat_id': chat_id, 'text': text} async with http_session.post(url_req, data= data, ssl_context=ssl_context) as resp: req = await resp.json() if limit.locked(): logging.warning("Concurrency limit reached, waiting ...") await asyncio.sleep(2) if not req['ok']: logging.error('Massage not sent. Error code: "{}".Description: "{}".'.format(req['error_code'], req['description'])) logging.info("Massage was send!") await http_session.close()

Good day. Yes, you was right. It is not AOIHTTP problem. My updates that i wrote in previous comment did not help. I tried to make curl of https://api.telegram.org from all my containers. But it does not have any results. But, google.com is accessible from any container. I think it is Docker and Telegram problems with proxy. I will try to fin a solution...

Hello, were you able to find a solution? I have the same problem with api.twitch.tv

[vikas-credgenics]

@MykolaBordakov : Did you find any solution. I am also facing the same problem.

@MykolaBordakov : Did you find any solution. I am also facing the same problem.

But how to get proxy_url and proxy_auth

[Ishaan1313]

Even i am facing the same issue but with discord now

[Dreamsorcerer]

OP said the problem was not aiohttp, so closing. Maybe someone has some ideas that can help you, but I would start by trying to curl or whatever in the docker image to confirm there's network access.
