Heads up for the URL to ping when on node version above 17

[Onokaev]

If you are on node version above 17, passing localhost as the url to ping might fail. Pass 127.0.0.1 instead.
For example if the URL you are pinging is on localhost, do not use http://localhost:port, instead, use 'http://127.0.0.1:port`
