I had an app that worked ok with 2 instances, both connecting to a single database. However, out of nowhere, one instance is no longer able to connect to this database.

Error: P1001: Can't reach database server at `postgres-85ae4b46.railway.internal`:`5432`

Please make sure your database server is running at `postgres-85ae4b46.railway.internal`:`5432`.

One of 2 instances connects alright and service is live with the latest commit. The other fails always, and causes the deployment state to show as Crashed.

If I press "Restart" on the container, it brings the whole service down.
