Getting OPT=15 error while querying 1.1.1.1

General

Having an issue resolving records on 1.1.1.1. On all other DNS servers I have tested (8.8.8.8, ISP DNS, DNS trace) I am able to pull the MX record for xdrtest.sandbox.dmhisp.com without issue. On 1.1.1.1, I am getting “OPT=15” error:

 dig xdrtest.sandbox.dmhisp.com mx @1.1.1.1

Any help or insight to this error is greatly appreciated.

Thanks!
