Hey all!

I’m attempting to connect an external visualization app to a read replica of my postgres instance. I’ve done the following

- Spin up a read replica
- Assign an IP address
- Expose the ports through this config:

```auto
[[services]]
  internal_port = 5432 # Postgres instance
  protocol = "tcp"

# Example of opening port 443 for secure connections
[[services.ports]]
  handlers = ["tls"]
  port = 443

# Example of opening port 10000 for insecure connections.
[[services.ports]]
  handlers = []
  port = 10000

```

That allows me to connect to the write replica. But if I try to point to the internal port at `5433` (which from my understanding [should point at the read replica](https://fly.io/docs/getting-started/multi-region-databases/#connect-to-regional-replicas)), the connection doesn’t work. I can, however, connect to the read replica through the internal connection (port 5433).

My goal is to only expose the read replica externally.

Any thoughts would be greatly appreciated.

Thanks!

Hello @td1

I want to achieve the same, just to expose the read replica.

Did you find the solution?

I want to the do the same thing to connect to the replicas externally. I would appreciate any help here.
