Main service can no longer connect to Postgres through internal networking

Question

Hi everyone, I have an app deployed on railway that has been working fine for a month straight with no changes.

All of a sudden, it seems like my main service is no longer able to reach my postgres service over the internal networking.

This is what I see in the logs from the main service:
```
Can't reach database server at `postgres.railway.internal:5432`
Please make sure your database server is running at `postgres.railway.internal:5432`.
```

and this is what I see in the postgres logs:
```
2025-11-27 16:26:30.683 UTC [92] WARNING:  pg_getnameinfo_all() failed: Temporary failure in name resolution
2025-11-27 16:26:30.683 UTC [92] LOG:  connection received: host=??? port=???

```

I have not made any recent changes that would have caused this.
