Trying to connect springboot application database with AWS RDS

I have a springboot application which runs locally perfectly. But I am trying to connect AWS RDS postgres from my springboot application with a free tier account. RDS Postgres is publicly accessible. Even I tried following YouTube tutorials and doing it the it the same way but it didn’t work.

WORKING – for local environment

spring.datasource.url=jdbc:postgresql://localhost:5442/postgres
spring.datasource.username=postgres
spring.datasource.password=postgres

NOT WORKING – with configured RDS while running app

spring.datasource.url=jdbc:postgresql://product-service.***********.amazonaws.com:5442/postgres
spring.datasource.username=postgres
spring.datasource.password=postgres

Error I’m getting while running springboot application

I got the solution after searching everywhere and watching videos.

I added security-group-rule with the below configuration, and it is now working perfectly fine.
