I'm running a Django web application and a Django-Q worker in separate deployments, both of which connect to a Postgres instance. This has been stable for months and no changes have been made for 4 months. Now I see this message repeated in logs:

django.db.utils.OperationalError: connection to server at "postgres.railway.internal" (fd12:83b6:c8e:0:1000:1f:4b9e:1615), port 5432 failed: Connection timed out

Is the server running on that host and accepting TCP/IP connections?

Is there a way to get the DB up and running (or accepting connections again)? Any idea why this would start happening?

Thanks!
