Some WHOIS servers choose not to make available domain data, and .li & .ch do this 😕

They do allow making a request only to see the availability of a domain https://www.nic.li/whois/domaincheck/#collapse-c25cbf2f-a663-11e6-89db-525400a7a801-1 and this would require making a request like this

const domainInfo = await whoiser.query({ host: 'whois.nic.ch, port: 4343, query: 'exampledomain.li' })

The response will be 0 or 1, meaning the domain can be registered or not. More info about responses can be found here https://www.nic.li/whois/domaincheck/#collapse-c25cbf2f-a663-11e6-89db-525400a7a801-2
