Hello Railway Team,

I have an update on my issue. I can now confirm this is a network-related problem on your platform for my project.

1. An API route with a simple console.log (/api/viral-radar) works perfectly. I can see the logs in my deployment.

2. The exact same route, when it contains a call to Google Firestore using the Firebase Admin SDK, fails with a gRPC Error 5 NOT_FOUND. The Admin SDK initializes successfully, but the first database call (.get()) fails.

3. The same full codebase deployed on a different platform (Vercel) does not produce this specific Firestore NOT_FOUND error (it has a different, unrelated issue).

This proves the function execution environment on Railway is fine, but there is a specific issue with outgoing gRPC requests to firestore.googleapis.com from my container.

Can you please investigate your egress network rules or any potential connectivity issues to Google Cloud Platform for my project?

Thank you.
