An invalid client error can be the result of multiple failure points on the client-side implementation. For a quick reference of the potential errors returned from the validation response, please see ErrorResponse.

Additionally, the most common occurrence is a mismatched client identifier between the following scenarios:

the client id provided in the authorization request (or the audience claim contained within the identity token of the authorization response); and
the subject contained within the client secret generated for the validation request.

Please see the Generate and Validate Tokens for additional information about the validation servers.
