Hi,

I have an application using google oauth2 to authenticate users, and I set the callback to a fastapi server so I can store the token for later use. I am trying to use railway internal networking to send this callback request from my react app to the fastapi backend, but I am getting errors that the POST request is timing out.

I'm using the generated internal domain name and port (8080) in my request. I can see that the backend is up and listening on IPv4 and IPv6 on 8080. However, since this is a callback URL, it will need to be an SSL endpoint.

First, am I missing something simple to get underlying connectivity up between these services? And second, is it possible to have the backend api behind HTTPS on the internal network segment?
