I have three C7 hubs. Two control devices. One controls the integrations and rules. Devices on the two device controller hubs are linked to the third controller using Hub Mesh. After the firmware update, all linked devices on the third controller hub show as "OFFLINE." Upon checking the Hub Mesh settings, I noted that the the two device controller hubs are NOT listed as "Active hubs."
I am running an Asus Zen wifi AX router. Multicast is disabled on the router. All hubs are ethernet connected with static IPs. I am NOT using Hub Login Security. This configuration worked just fine until I updated firmware.
Did you update all three hubs to the latest firmware? Depending on what previous release your hubs were/are running, they may now be a mismatched set. If not, make sure all three hubs are upgraded to the same version.
I'm running both Firewall and stingBox on my network. I'm only blocking port 8443, There have been no configuration changes to these devices. Again, my hub mesh was working until I upgraded the firmware yesterday. Thank you again for all those offering assistance.
All three hubs are directly connected to a NetGear GS324 gigabit switch which is connected directly to my router. I also confirmed that monitoring of the hubs was turned OFF on my firewall (apparently I did this sometime in the past). What port is being used by Hub Mesh?
While I appreciate everyone's efforts, this issue remains unresolved. I have disabled my firewall and stingbox and rebooted the hubs and they still don't display as active hubs on the hub mesh settings page. Again - the hub mesh worked until I updated all the hubs to 220.127.116.11. I remain concerned that something in the update is the root cause of the problem.
