Telegram – PythonAnywhere – OSError: [Errno 101] Network is unreachable

This code for a Telegram bot was working previously on pythonanywhere until someone took it down accidentally, now trying to upload it again, but facing some errors. I’ve tried turning off my firewall to fix the error, but I’m not very well versed in Python, so I’m not sure if there’s something missing in the code or it’s completely a network issue, for which I also don’t know how to fix. This is the bot.

OSError: [Errno 101] Network is unreachable

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

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:
OSError: [Errno 101] Network is unreachable

The above exception was the direct cause of the following exception:
aiogram.utils.exceptions.NetworkError: Aiohttp client throws an error: ClientConnectorError: Cannot connect to host api.telegram.org:443 s

I’ve tried turning off my firewall to fix the error, but I’m not very well versed in Python, so I’m not sure if there’s something missing in the code or it’s completely a network issue, for which I also don’t know how to fix. I’ve visited multiple forums to no avail, any help is much appreciated. I’m using a free account on pythonanywhere. Btw, but this hasn’t been an issue before.
