sequelize and react won't connect postgresql without an error - node.js

Question

I have a react app with express server. It's not working on one of my pc(others are fine exact same versions and setup). Problem is even though i can connect to my postgresql db both from terminal and pgadmin interface, neither express server or sequelize can't find/connect it and they don't produce any error. sequelize db:migrate finishes without an error or additional migration/table created message. This leads infinite loading on app but all pending requests eventually fail.
Here is my sequelize config file:
{
"development": {
"username": "postgres",
"password": "postgres",
"database": "db",
"host": "localhost",
"dialect": "postgres",
"port": 5432
},
"test": {
"username": "postgres",
"password": "postgres",
"database": "db",
"host": "127.0.0.1",
"dialect": "postgres",
"port": 5432
},
"production": {
"username": "postgres",
"password": "postgres",
"database": "db",
"host": "127.0.0.1",
"dialect": "postgres",
"port": 5432
}
}
and react config in .env and express server
.env
DB_PASSWORD=postgres
DB_PORT=5432
DB_DATABASE=db
DB_HOST=localhost
DB_USER=postgres
server.js
const connectionString = `postgresql://${process.env.DB_USER}:${
process.env.DB_PASSWORD
}#${process.env.DB_HOST}:${process.env.DB_PORT}/${process.env.DB_DATABASE}`;
sudo systemctl status postgresql.service returns this:

I've been trying to fix this issue and finally found a solution.
If you are using Node v14 just like me, you need to update pg module from npm and that's all
