Unable to authenticate: invalid_grant

[scaarup]

Hi.
I am able to authenticate on https://www.miele.com/developer/swagger-ui/swagger.html#/ with the creds I have defined in configuration.yaml, but the integration has stopped working. FYI, yesterday there was a firmware update for my dishwasher.

I have tried to delete the integration completely, several times. I have generated new credentials also. I keep getting this error:

I am also getting the same error after not using home assistant for the last 2 months.
Here you can find the log:

During handling of the above exception, another exception occurred:

I got this resolved.
What I eventually think did the trick, was this
cache_path: /config/miele_token
I was unable to locate the "default" token file, but I suspect there was some sort of invalid token file present on the system. (the cache_path must point to a file, not a directory. This is not mentioned in the documentation).

thank you!

Where is the cache_path defined?

In your config - optional.
