Discord.py: Issue after closing bot and restarting it

[Caedous]

Summary

I get a very long winded error message when I go to open my bot.

Reproduction Steps

I simply open my bot and get an error. I have updated to the latest version of discord.py

Expected Results

The bot to run without any issues as it had been prior to closing it

Actual Results

This appears to be the SSL certificate error on Windows. Check out #4159 for some solutions that might help you fix this.

I am currently having the same issue here, I am using macOS

EDIT: certifi needed to be updated. Can be done on macOS by navigating to Applications/Python3.8 and double clicking the Install Certificates.command

There should be mac solutions in #4159

Downloading that missing certificate solved my issue. Thanks!
