Unsolved Domain setup shows 'queryNs ESERVFAIL'

[klfc556]

I have installed Cloudron in my server, and then went to the Domain Setup page

After typing in domain, DNS Provider and API Token, I clicked 'Next'

But the page wouldn't process and showed 'queryNs ESERVFAIL'

@klfc556 does that domain contain any special characters? Also can you query the nameservers from your server if you are logged in via SSH?

This can be done for example with host -t NS example.com
