OAuth 2.0 error access_denied

[Gintarevvv]

I'm getting an Aouth02 error:

{ "error_description": "access_denied", "error": "server_error" }

I set it up according to the instructions, OAuth 2.0 with Inbound REST - ServiceNow Community and it works in lower environments. What could be wrong?

error in system logs: "Exception on token flow - invalid_scope: The provided OAuth token is not valid: no thrown error"

Had the same issue. Realized that this error is thrown when the client_secret doesn't match.
