Hi Manos,
I'd first check that the service is enabled on the pre-configured tool (Site admin > External tool > manage tools > edit tool settings). There's a "Services" section in the form which contains "IMS LTI Assignment and Grade Services" which must be set to "Use this service for grade sync and column management". If this isn't set, then you won't be able to access those services. Then, the only other thing to make sure is that you're requesting the token with the relevant scope.
Hope that helps,
Jake
