Failed to authenticate to external api via Oauth2

Forge

I am having issues setting up External Authentication to Tempo. When going through the Oauth workflow, I always end with this message.

‘Failed to Authenticate’

However… if I take the code that is returned on this screen (grabbing it from the developers tools network tab) and plug it into Postman, I am able to successfully obtain a token and make requests to the Tempo API.

So I’m confused as to why this is working in Postman but not in my Forge app. Here is the code in my manifest.yml file.

modules:
  jira:dashboardGadget:
    - key: dashboard-with-tempo
      title: dashboard-with-tempo
      description: Getting Tempo Data to show up on the dashboard.

Any help here would be appreciated.
