Gateway accessing web/sharepoint

Hi, 

I am facing a following error when trying to refresh dataset in Service. It works fine on desktop:

• Data source error{"error":{"code":"DM_GWPipeline_Gateway_MashupDataAccessError","pbi.error":{"code":"DM_GWPipeline_Gateway_MashupDataAccessError","parameters":{},"details":[{"code":"DM_ErrorDetailNameCode_UnderlyingErrorCode","detail":{"type":1,"value":"-2147467259"}},{"code":"DM_ErrorDetailNameCode_UnderlyingErrorMessage","detail":{"type":1,"value":"Web: Request failed: [HERE IS A LINK TO FILE ON SHAREPOINT]/_api/contextinfo"}},{"code":"DM_ErrorDetailNameCode_UnderlyingHResult","detail":{"type":1,"value":"-2147467259"}},{"code":"Microsoft.Data.Mashup.ValueError.DataSourceKind","detail":{"type":1,"value":"Web"}},{"code":"Microsoft.Data.Mashup.ValueError.DataSourcePath","detail":{"type":1,"value":" [HERE IS A LINK TO FILE ON SHAREPOINT]/_api/contextinfo"}},{"code":"Microsoft.Data.Mashup.ValueError.Reason","detail":{"type":1,"value":"DataSource.Error"}}],"exceptionCulprit":1}}} Table: Final Table (3).

  When connecting to that data source as a seperate dataset, it works okay, no error in refresh.
  Gateway configured correctly, 

  

  All credentials are setup as organizational both in web as in desktop.
  I think I've already tried everything and just cannot locate issue, error message is also not helpful.
