Codestream: Jetbrains :: CodeStream Panel Empty. Slack API Error Found In Log.

Describe the bug
When I started PHPStorm today the CodeStream panel was completely empty and there was no way to do anything via the UI and no indication of what could be wrong. There is a Slack API error in the log though:
