node.js app on ubuntu linux with postgresql on virtual box on windows client

I set up, ubuntu linux on virtual box. Then I installed postgresql and node.js So basically I made a clean installation and i want that ubuntu handles my requests. When i run node server.js , a Sequelize.js error occurred.

Unhandled rejection SequelizeConnetionRefusedError: connect ECONNREFUSED 127.0.0.1:5433

PostgreSQL is listening on port 5432, and once i run node server.js,tables are created with no problem.

I think is a problem with my client, and I don’t know why.

postgres.conf listen_addresses=’*’.

pg_hba.conf host all all 0.0.0.0/0 trust.

I have little bit experience with Linux Ubuntu and configuration So a big hug and thanks for who will help me
