This turned out to be a server networking issue. Using another server makes it all work.
Hi, I have the same issue here, in the domain setup page, it stuck with the message queryNs ESERVFAIL <domain>, and wouldn't process to the next step
I type in host -t NS <domain> in my server, the returned message is Host <domain> not found: 2(SERVFAIL)
My server is Vultr, and the domain is hosted in Vultr as well
How can I solve this ?
