sequelize db:migrate fails on localhost without internet connection

On my win10 laptop, in airplane mode:

> sequelize db:migrate

Sequelize [Node: 6.9.2, CLI: 2.7.0, ORM: 3.30.4]

Loaded configuration file "config\config.json".
Unable to connect to database: SequelizeConnectionError: getaddrinfo ENOENT localhost:5432

Works fine as soon as the WiFi reconnects.

My config.json:

{
	"username": "postgres",
	"password": "password",
	"database": "whatever",
	"host": "localhost",
	"dialect": "postgres"
}

If I replace “localhost” in the config file with “127.0.0.1”, the problem does not occur.

I also had this issue, and it was fixed by replacing to 127.0.0.1
