Is this due to Asana? or my browser??
I have struggled with this issue for a few days already, so let me know if you have any clue about this.

Changed ‘https’ to ‘http’, then it worked.

When I implemented GitHub OAuth 2.0, https://localhost:3000/ was fine for localhost, but not for Asana, it seems it has to be http://localhost:3000/.
