Again .br domains lookup not working due to WHMCS using incorrect hostname

[jasspuri121]

Again i'm here with same problem. 

WHMCS comes with whois.dist.json pointing whois.nic.br for .br domain lookups. While this also worked for some years, the official WHOIS service (as can be seen in https://www.iana.org/domains/root/db/br.html) has always been whois.registro.br. An architecture change removed whois.nic.br from the DNS, which has been causing availability check errors in WHMCS installations. 

While a new DNS entry has been added to make whois.nic.br resolve again, now as a CNAME, it might take some time for some resolvers to catch up. And either way, this was a WHMCS error that WHMCS needs to fix. 

For now, either try refreshing resolver cache for whois.nic.br, or add a whois.json to point .br either to whois.registro.br, or to a simplified availability check:

{
	"extensions": ".com.br,.net.br,.eco.br,.art.br,.adv.br,.eng.br",
	"uri": "https://registro.br/v2/ajax/avail/raw/",
	"available": "\"status\":0"
	}

Any feedback?

The CNAME chain is still there:

 

host whois.nic.br

whois.nic.br is an alias for whois.registro.br.

whois.registro.br is an alias for rdap.registro.br.

rdap.registro.br has address 200.160.2.80

rdap.registro.br has IPv6 address 2001:12ff:0:2::80

 

If you try "telnet whois.nic.br 43" at the console of your server, what happens ? 

 

That said, I surely hoped that by now WHMCS already fixed that by changing to whois.registro.br. And I strongly suggest you do it yourself in whois.json.
