I did the http://learnforge.autodesk.io tutorial and locally the apps work fine. But when I try to deploy the forge.tutorial.viewhubmodels.nodejs app to Heroku I get the following error when I try to log in:
GET https://forgebcsample.herokuapp.com/api/forge/oauth/token 401 (Unauthorized)
The Config Vars are correct in the Heroku dashboard and I updated the values at the Forge Developer Portal as it is described in the tutorial under deployment. I even tried hardcoding the FORGE_CLIENT_ID, FORGE_CLIENT_SECRET and FORGE_CALLBACK_URL into the app but the error still persists.
