Getting a "getaddrinfo ENOTFOUND fall" error when trying to start the Experience service.

Installed an on-premise experience service and trying to start it using

sudo ./start-es.sh

but getting the error below.

Error: getaddrinfo ENOTFOUND fall
at GetAddrInfoReqWrap.onlookup [as oncomplete] (dns.js:64:26) {
errno: 'ENOTFOUND',
code: 'ENOTFOUND',
syscall: 'getaddrinfo',
hostname: 'fall'
}

}

What could the reason be and where should I check
