sub domain in Route 53 not working in local network

Hello.

From my network, name resolution appears to be working properly.
Is there a possibility that there is a problem with your local network's DNS settings?

dig app.mergetemps.com

I can resolve your domain and sub-domain from any third party domain tool box like [1][2][3]

I checked that your NS records are normal and work properly. It's suggest you check the DNS configuration of the local network like static rule in /etc/hosts or contact the administrator of local dns resolver to further confirm whether they have an overwrite or customer forwarding rule for this domain.
