Im running a nextjs application in a STAGING environment that builds successfully - however once it deploys it cannot connect to my STAGING postgres DB that I'm running.

NextJS app keeps saying this:

Error: P1001: Can't reach database server at postgres.railway.internal:5432

Please make sure your database server is running at postgres.railway.internal:5432.

error: script "start" exited with code 1

$ bun x prisma migrate deploy && bun --bun next start

Loaded Prisma config from prisma.config.ts.

Prisma schema loaded from prisma/schema.prisma.

Datasource "db": PostgreSQL database "railway", schemas "auth, public" at "postgres.railway.internal:5432"

Error: P1001: Can't reach database server at postgres.railway.internal:5432

Please make sure your database server is running at postgres.railway.internal:5432.

The postgres logs dont show any attempt at an incoming connection. Everything has been upgraded to metal also - I'm about to try the public Database URL to see if that works, however shouldnt the private one be fine?

Ive tried reference variable ${{Postgres.DATABASE_URL}} and hard coding the string.
