401 when getting installation token

This error mostly likely means that the JWT used to authenticate as the application is invalid, but there are several reasons that could happen. It's hard to know what the issue is from the logs, so here are few things to check:

1. Confirm that the github.app.private_key value in the configuration is correct
2. Confirm that the github.app.integration_id value in the configuration is correct

If you believe both of those are correct, you can test out the authentication process manually using the script and steps documented here: https://developer.github.com/apps/building-github-apps/authenticating-with-github-apps/#authenticating-as-a-github-app

If both of those values are correct and the manual authentication works, the next thing to check is that the clock on you GitHub instance is synchronized with the clock on the machine running PolicyBot. If the machine running the bot is more than one minute off from GitHub in either direction, it's likely that the issued or expiration times of the JWT will be invalid.

My server was off by 4 minutes - Timedrift :(
Thanks so much! I'm finally getting policy-bot status checks on my PR's
