AppDaemon won't authentication with a token

Moved to 0.85 tonight and removed all my legacy password stuff.
Created a new user for AppDaemon and created a long-lived access token for that user.
Upgraded AppDaemon to 3.0.2
Replaced ha_key in appdaemon.yaml with token

However it still won’t connect:

2019-01-13 20:43:55.219949 WARNING AppDaemon: HASS: Disconnected from Home Assistant, retrying in 5 seconds

Any ideas?

Ugh seems you need to restart HASS after creating the token or something, as that sorted it…
