Error with authorization token request

[bg24]

My openhab was runnng with the new API. Since some days I recognized following failure messages:

21:00:00.692 [ERROR] [hab.core.model.script.viessmann.rules] - Cannot get values from Viessmann IoT API. Access-Token is unavailable.

21:00:01.311 [ERROR] [hab.core.model.script.viessmann.rules] - Cannot update the authorization tokens. Error: {"error":"invalid-token-request"}

Any suggestions where to start searching in order to find the root cause?

Hello @bg24 ,

Please check whether your refresh token is still valid. The refresh token has a lifetime of 180 days and if your integration was running before, I assume the reason is that the refresh token is not valid anymore.

Best,

Michael
