Cannot connect to the databse

Hello, I was using Wappler for the past few weeks and now I am facing difficulty in connecting my project to the database that I will need to be working on.

At first, I was having difficulty connecting the AWS to the Wappler docker target, but I went through
this document.

However, when I try to connect(use) database it says that “connect ECONNREFUSED (numbers)”

I guess I am wrong with something in this tab, but I’m not sure what should I input on the sections on the database tab. Additionally, I am currently working with AWS RDS

You need to add in where you database is in the Database URL, otherwise how can it find it?
Use either a domain or IP address and make sure the port is correct.

I tried various approaches but I’ve realized that it works when I go through this document
