ConnectionResetError: [Errno 104] Connection reset by peer

Hi there,
We've been using botogram for a while and it works great ! ... except.

Since we moved our systems in docker containers run on AWS, we get the following error after some time :

Traceback (most recent call last):
  File "/usr/local/lib/python3.9/site-packages/urllib3/connectionpool.py", line 703, in urlopen

During handling of the above exception, another exception occurred:

It seems to me that the connection to the telegram API is someone getting rejected by telegram, but I can't do anything about it, right?

We used to run that on a "normal system" and it worked great.

Any idea why this could happen now? Or a workaround ?
