Why is the python telegram bot shutting down?

Question

Bots

writing a bot and using pyTelegramBotApi in Python!

The problem is the following: The
bot is turned off and there is the following error:
requests.exceptions.ConnectionError: ('Connection aborted.', ConnectionResetError(104, 'Connection reset by peer'))

Telegram is already unblocked in Russia! So not because of blocking, apihelper does not help ...

I googled, but I did not find any new solutions other than apihelper

Complete error

Answer 1

The fact that it was unlocked does not mean that this is not the problem.
Everything is purely a connection error, so think about how to fix it.
Very slow Internet is possible

Answer 2

Faced a similar problem - the bot crashes with this error if you write to him after a long period of silence. The problem here is that at some point the session times out; if after this moment the bot tries to send a message, it will crash with an error. Analysis of this situation - here https://github.com/eternnoir/pyTelegramBotAPI/issu... , the solution is also given there - register
apihelper.SESSION_TIME_TO_LIVE = 5 * 60
If this is done, a session older than five minutes will be considered inactive and restarted; an alternative is to wrap each bot.send_message in a try and try to resend the message after failure.
