I have deployed an Umami service and assigned the umami.railway.internal domain to it.
However, when another service tries to access http://umami.railway.internal:3000, it encounters a "connection refused" error.
I attempted to start the same Umami server within a Docker container on my local machine, using the same environment variables, and had no issues accessing http://localhost:3000.
Therefore, I suspect there might be a problem with the private networking configuration.
