Maybe I can find answers to my question here in the community.
I run a somewhat more complex music bot and this got set up on a fresh server today.
Problem
I've been using Heroku for this bot for a while now and so far there have never been any problems. I then tried to set everything up again today because my hosting time has expired, starting it up also worked fine. But now the following:
I made the following changes in my requirements.txt file:
discord.py == 1.6.0
youtube_dl == 2021.1.16
Together with these settings the bot doesn`t even manage to hold out for 2 minutes and play the music properly. I always got only the following error message:
Shard ID 0 heartbeat blocked for more than 10 seconds.
I reported to the discord.py server, but on version 1.6.0 such changes causing this error were not introduced. So I thought that the problem is with the youtube_dl version. So I kept trying around, set discord.py == 1.5.1 and youtube_dl == 2021.1.8, but again Heroku seems to stop working at some point and now I get the following error code:
WARNING] discord.gateway: Shard ID 0 has stopped responding to the gateway. Closing and restarting.
The bot stops responding, takes too long to start and I have to restart it manually. The funny thing: I also have a bot, which is only on one server and also runs via Heroku, there the errors also occurred, even with my old "settings", when the bot was still running on Heroku.
The latest and longest error I got:

To the Python buildpack I have installed the following things:
https://github.com/xrisk/heroku-opus
https://github.com/jonathanong/heroku-buildpack-ffmpeg-latest
Could the error be due to these buildpacks, although it always worked before? I just don't know at the moment, because of course everything works locally. Also upgrading to newer modules or versions from my requirements.txt file always causes problems with Heroku or doesn't let the bot start.
Is there a recommendation which python version to use with Heroku? Currently I define with a runtime.txt the version 3.7.9.
