I am trying to make a connection nexus repository with PostgreSQL but connection fail every time

Error: 2021-08-20 17:25:04,563+0500 ERROR [FelixStartLevel] \*SYSTEM com.zaxxer.hikari.pool.HikariPool - nexus - Exception during pool initialization.  
org.postgresql.util.PSQLException: The connection attempt failed.

I have tried the EKS use-case mentioned in nexus documentation it’s not showing any error but Postgres not attach with nexus

is there any resources or guideline for Postgres connection with nexus repo pro?
