Deploy failing because of DB not running

Hi team,

My deploy is suddenly failing because of the following error:

Datasource "db": PostgreSQL database "guerdon_v2", schema "public" at "top2.nearest.of.guerdon-v2-db.internal:5432"
	 Please make sure your database server is running at `top2.nearest.of.guerdon-v2-db.internal`:`5432`.

But I can see from the dashboard that the DB is in running status.
