Power BI Refresh Issue DM_GWPipeline_Client_OAuthTokenRefreshFailedError

[hofax]

After going through Power BI Support and creating a ticket they were unable to help and directed me to open an issue here...so here is goes again.

I have create a connector that uses OAuth2, login and and token refresh work as expected in both the desktop app and the online service with the caveat that if I have more just one query that uses my connector as the data source then the refresh fails on the second query with the a DM_GWPipeline_Client_OAuthTokenRefreshFailedError error.

My connector uses a dynamically built navigation table to create a list of folders which a list of tables within each. All build so that the structure is built as follows. GET /projects, enumerate the projects to get their underlying tables (really just a json array), GET /projects/views, then to load the actual view data GET views/1.

I'm happy to provide more detail as well the data connector code. Please advise.
