[PROBLEM] No Receivers Discovered

[downriver_bob]

Right, I changed it back to "Problem" from "Solved" but the symptoms suggest a network issue thats external to moode software.

You should prolly post more info about your network configuration. Maybe it will provide some insight into what might be blocking the nmap scan.

Residential Routers typically only filter traffic between the local network and public Internet while allowing all packets to pass between local network hosts. On local WiFi, multicast traffic is enabled by converting it to either broadcast or multi-unicast (multicast to unicast).

Sure, I gather it is more a network problem also, but not understanding what the error is showing I'm not too sure.

I run a Unifi network, separated into VLANs. All Moode nodes are on the same VLAN so traffic shouldn't be block between them. There are a few basic firewall rules configured, but even with everything disabled, I still have the same issue.

IGMP snooping and mDNS are enabled across all VLANs.

I am running all Moode nodes on wired etherent.

Is there any other info that is relevant that I may have missed?
