Unique IP address required for host


I’m trying to update my nameserver with https://whc.ca/en, I can add the free2 nameserver fine but the free1 nameserver returns “Unique IP address required for Host”. Since I need at least 2 nameserver it becomes an issue. I submitted a ticket to tech support on whc.ca but wonder if it is something on this end as there was no issue with hosterbox’s nameservers, anyone else have this problem?


here is the response from whc

Thanks for reaching out to us. It appears that the issue is coming from the DNS you’re trying to use. I successfully changed your domain’s DNS twice using different nameservers. Everything went through as expected.
Would you mind double-checking the nameservers you’re trying to use with your current host provider? Are they correct?
