Can't find Token in the log file - Says ERROR Service Unavailable

[Azzhoe]

when looking through the log file, it seems it can't access something and gives me an ERROR Service Unavailable.

Here's the error I get (with redacted instance id):

[Nest] { Error: SERVICE UNAVAILABLE: {"error":"service unavailable","type":"https://developer.nest.com/documentation/cloud/error-messages#service-unavailable","message":"service unavailable","instance":"aaaaaaaa-bbbb-cccc-dddd-eeeeeeeeeeee"}
