I am hosting this bot on K8S and it always ran into this error and caused the bot stopped response:

Every time i need to fix it by restarting the pod

I have done some research online they said upgrading the httpx modules helps, but i don't familar with this package.

I created branch http-version with possible fix of your problem. To apply updates:

git pull
git checkout http-version

Please, write here if it helps or not.
