Automated Database Testing with Nightwatch JS

Hi guys i was trying to change the defauly browser in nightwatch.conf.js (nightwatch generated file) I want to use chrome and I did all the proper config to use chrome from webdriver installation to changing of ports but whenever i am compiling and running the test I keep on having the connection refused error message and it seems like it keeps on connecting using the default host and port configuration of geckodriver. Please help me im a beginner in Automation testing thanks
