Connection to localhost:5432 refused on nifi UI

Hello. Im currently running nifi and postgresql on docker compose. I have a problem setting up the DBCPConnectionPool controller. I keep getting the error message below.

Below is my configuration for DBCPConnectionPool

I have checked the db name and docker compose yml file but nothing seems wrong on that end. What could be causing the problem here?

Ok just in case anyone is suffering from the same problem as me.

Since I am running this on docker compose,

instead of localhost:5432, I changed it to <container name>:5432 and its working now
