I’m having “random” issues with HAOS and Thread/Matter on my network. At random times mDNS will fail and the Matter server logs are full of mDNS timeouts. Generally either doing a full reboot of the HAOS VM or power cycling both ATVs, or rebooting all 3 devices, resolves the issue. Then the logs will be clean for a couple of days, then mDNS issues crop up again. Everything is on a single internal network. IGMP snooping is disabled on all physical switches, as turning it on caused issues with Proxmox and having the “VLAN aware” setting on the bridge checked.
Configuration:
-HAOS 2023.10.1 VM
-Proxmox 8 host - single physical NIC
-Firewalla Gold Plus router
-Two Apple TVs w/ thread, tvOS 17
-Apple TVs use wired ethernet, as does the Proxmox host
-No SkyConnect
-Everything on a single subnet
-IPv6 DHCP enabled on Firewalla
-QNAP and Netgear switches, IGMP snooping turned off
-Ruckus R650 WAPs
The mDNS issues seem “random”. Sometimes I reboot the HAOS VM and immediately after reboot the logs are filled with mDNS timeout issues: CHIP Error 0x00000032: Timeout
Then I reboot the HAOS VM again, and the Matter logs come up clean and life is good. It’s very frustrating. This issues seems to have gotten worse the last couple of weeks. I know mDNS issues are likely network induced, but I’m not sure where to start diving to get to the root cause.
Reviewing the Thread diagnostics in HAOS, the JSON does show my two ATVs and the route to both. In case it’s a Proxmox issue, here are some sysctl dumps for the IPv6 settings. vmbr0 is the bridge and enp87s0 is the physical NIC. On the Ruckus APs I have the settings that convert multicast to unicast all disabled.
Any help would be greatly appreciated!
