ECONNREFUSED error when connecting to mongodb from node.js

by

ECONNREFUSED error

There are few reasons of this error in node :

  1. Your port is already serving some service so it will refuse your connection.

    go to command line and get pid by using following command

    $ lsof -i:port_number

    Now kill pid by using

    $ kill -9 pid(which you will get by above command)

  2. Your server is not running e.g. in this case please check your mongoose server is running or run by using following command.

    $ mongod

  3. There is also possibility your localhost is not configured properly so use 127.0.0.1:27017 instead of localhost.
