Hello Railway team,

I am facing an issue with my Postgres service.

- When I try to connect using the generated .proxy.rlwy.net domains (e.g., switchyard.proxy.rlwy.net:5432), I always get DNS resolution errors (NXDOMAIN).

- nslookup also fails to resolve these .proxy.rlwy.net hosts.

- However, the *.up.railway.app domain works fine.

- Logs show repeated: "invalid length of startup packet" whenever connections are attempted.

I need clarification:

- Are .proxy.rlwy.net domains still supported for external connections?

- Should I use only the *.up.railway.app domain or the internal postgres.railway.internal inside the same project?

Thank you!
