Sorry you're experiencing issues. We will get some more eyes on the above to see what might be wrong. In the meanwhile, I suggest taking a look to https://github.com/AzureADSamples/WebAPI-ManuallyValidateJwt-DotNet and in particular global.asax.cs - that's the sample where we feature raw use of the JWT handler.
