glue_host_not_registered
Glue host not registered. The HTTP status depends on the call.
A nameserver in the request is a .se or .nu host that is not registered at the registry. For .se and .nu domains, such a nameserver must exist as a glue record before it can be used.
What to do
Register the host first. If its domain is in your account, add it with POST /api/v2/domains/{id}/glue-records on that domain; otherwise ask whoever manages that domain. Or use our nameservers primary.ns.hostup.se and secondary.ns.hostup.se.
Branch on code, not on title or detail. When you contact support about it, include the requestId. More in Errors and retries.
