NS records on subdomain not propogating

What is the name of the domain?

aws-dev.timetopet.com

What is the issue you’re encountering

I have added new NS records to delegate the subdomain aws-dev.timetopet.com, but these are not propagating.

What steps have you taken to resolve the issue?

I have tried deleting all records and re-adding, but this hasn’t helped.
Running dig +noall +answer aws-dev.timetopet.com ns returns nothing.

What feature, service or problem is this related to?

DNS not responding/updating

The delegation is working due to the NS records you have added to Cloudflare but you can’t resolve the NS (or other) records as those AWS nameservers aren’t resolving for your subdomain yet.

Thanks sjr, that pointed me in the right direction. Turned out to be a typo in our AWS configuration :+1:
