mDNS

Hi,

is there a way to making the Mdns work when this is running in Docker desktop?

Same problem here, running nmos-cpp registry in Docker 28.0.1
(on an Debian 12 / Linux 6.1.0-31-amd64 as a vm on Proxmox 8.3.4, single instance (no cluster)).

When I add the IP from the registry to an endpoint I can connect and its working fine. But with some devices there is no option to point them to a registry (they need mDNS).

Please share initial logs from the registry.

@garethsb thanks for getting back that quick. We actually rechecked everything and it was the "forward unknown multicast" setting in the physical switch in the testbed that would drop our DNS. Since we are now forwarding unknown mc at the switch level also the registry is announcing itself via mDNS. So all good..

@soundiesam is this problem specific to Docker Desktop? If yes maybe share details.
On Docker on Debian 12 mDNS running fine.
