Kumo API: Unable to acquire a security token.

[panhansm]

I see constant entries like this in my home bridge log:

[9/9/2022, 10:34:36 AM] [homebridge-kumo] Kumo API: acquiring a new security token.
[9/9/2022, 10:34:37 AM] [homebridge-kumo] Kumo API: Unable to acquire a security token.
[9/9/2022, 10:34:37 AM] [homebridge-kumo] Workshop (queryDevice): failed.

Using home bridge on Mac V1.5.0 and homebridge-kumo v1.9.1

Surprisingly the control of my AC still works in direct as well as indirect mode. Any idea what I might have missed or is this indeed a bug?
