pythonanywhere doesn't work. What to do?

Question

Python

I'm running a telegram bot on pythonanywhere and it throws an error:

18:20 ~ $ python t2bot.py
WARNING:aiogram:Goodbye!
Traceback (most recent call last):
  File "/home/levman/.local/lib/python3.9/site-packages/aiohttp/connector.py", line 969, in _wrap_create_connection

  File "uvloop/handles/tcp.pyx", line 204, in uvloop.loop._TCPConnectRequest.connect

The above exception was the direct cause of the following exception:

    raise client_error(req.connection_key, exc) from exc
aiohttp.client_exceptions.ClientConnectorError: Cannot connect to host api.telegram.org:443 ssl:default [Network is unreachable]

During handling of the above exception, another exception occurred:

aiogram.utils.exceptions.NetworkError: Aiohttp client throws an error: ClientConnectorError: Cannot connect to host api.telegram.org:443 ssl:default
 [Network is unreachable]

And everything worked locally.
Where is the mistake?

Most likely you have a free version of hosting, and it has limitations.
