Changing account following testing

[orangehand]

All was fine in testing using our account on the customer's pfsense. However I cannot get it to change to use the customer's account.

Changed the auth key and did the red button flush, but now get this error: Error executing command (/usr/local/bin/tailscale status)

Health check:

- state=NeedsLogin, wantRunning=false

Logged out.
Can you advise how I sort please?
