Describe the problem/error/question

For the last past month, when adding the Slack and Github nodes (haven’t tried other nodes yet), after following all the steps in the doc, I get an unauthorized answer that opens up in the new pop-up window.

What is the error message (if any)?

In the pop-up window:
https://.railway.app/rest/oauth2-credential/callback?code=7367341133045.7376072410243.938f7f13adae2722d9f10de2d3b4cdd61c83b8278e6809bcae4f6b5f571c299d&state=eyJ0b2tlbiI6IkdRQkEwV1BWLU5YZVRZdkZHVjU1dTdSMkZPOER4dEVJUTNoUSIsImNpZCI6ImdSSDI4SHliTnlFWmNHeDQifQ%3D%3D

I get an:

unauthorized

Hello, thanks for your answer and help. This fixed my issue.

For further reference, in the new deployed version using railway, the URL callback is actually the custom domain instead of the deployment base URL.
