Hi, we have been using OAuth for our staging and production environment. Since this morning, we can’t seem to authenticate anymore, even if our code base and set up for our staging environment hasn’t changed.
The error we get is:
{\"error\":\"invalid_client\",\"error_description\":\"Client authentication failed (e.g., unknown client, no client authentication included, or unsupported authentication method). passwords do not match\"}
I wonder if there is anything going on on your authentication process ahead of the maintenance scheduled in a couple of hours, according to https://status.nuki.io?
