Hi,

I have a project with 2 services: cms -> Strapi, web -> an Astro website and a Postgres DB. I'm using Railpack for both services.

I have managed to deploy the Strapi service, and is accesible through the public URL so I can add new data, is working properly, I can also access the API from my local development environment and get the data without any issue.

I have deployed the Astro website (I have follow the documentation https://docs.railway.com/guides/astro), but it is not able to get data from the Strapi service using the private network, I have configured the host in both services to 0.0.0.0 as mentioned in the documentation, and I'm using this to set the STRAPI_URL variable for the Astro website: =http://${{cms.RAILWAY_PRIVATE_DOMAIN}}:${{cms.PORT}} but this not working, instead if I set the variable to: https://${{cms.RAILWAY_PUBLIC_DOMAIN}} it works as expected, the Astro website is able to fetch data from the CMS.

The deploy logs show that the Astro website starts properly:

 [@astrojs/node] Server listening on 
  local: http://localhost:8080 	
  network: http://xx.xxx.xx.xx:8080

But when accessing the public URL I get a 500 error and in the logs I get this:

[ERROR] TypeError: fetch failed

am I missing something here to be able to connect both services using the private network?
