ASUS ZenWifi AX (XT8) mesh: devices only accessible if on the same node

[1200lle]

I am so frustrated and desperately need help. Using a mesh build by four Asus ZenWifi AX (XT8) routers. One “main router” connected to incoming Ethernet and three nodes connected over WiFi to the main router.
Have two different devices (one music streamer and one IKEA Tradfri gateway for lightbulbs) with the same problem. They are only accessible from my iPhone if the phone is connected to the same node as the device.

Firmware is updated.
Multicast is enabled (solved the same issue for some other devices).
All IP-addresses are 192.168.50.xyz.
Smart Connect enabled.
AP isolated is disabled.

Does anyone have a solution?

Any VLAN on the network for anything? Only one node does this, or if you switch up two nodes, they are behaving the same? On the router can you see the devices on the AiMesh menu, on the client List? What are your settings from the wireless tab, and from the wireless > professional tab? -Without the sensitive data like your SSID and PW

- I’m not too good at this but not that I’m aware of .

- Same problem on all nodes.

On the router can you see the devices on the AiMesh menu, on the client List?
- Yes

What are your settings from the wireless tab, and from the wireless > professional tab?
- Attaching screenshots!

Thanks a lot for your help!

Sorry for the late answer. Did you tried to disable the IGMP Snooping? ("Aktivera IGMP snokande")
That would be my first try.

Yes I did. Unfortunately it did not solve the problem and also I experienced new problems with another device (Bluesound multiroom music streaming which works fine)
Thanks!
