I have a few new clusters running Consul v1.9.1
Consul is definitely up, the UI works. I can register services, but using the DNS interface for discovery just yields the below.
$ dig @127.0.0.1 -p 8600 consul.service.consul ANY

Happy to provide any information required. This is absolutely baffling as I can see from the logs :
[DEBUG] agent.dns: request served from client: name=consul.service.sandbox.consul. type=A class=IN latency=1.653581ms client=127.0.0.1:52840 client_network=udp
even stranger is that recursion works fine
