Unable to Add/Pair my new Cube Air X3 nodes to my existing Halo Pulse 3 network

I am having trouble pairing my new Cube Air X3 Mesh nodes to my existing Halo Pulse 3 System. I have the new Node positioned less than 6 inches from the Pulse Main Router Node. and It will not pair, and I cannot do an add through the app or my computer logged into the Wavlink itself.. the new Cube Nodes are never found. I have tried all 3 nodes all with same result. No Bueno.

I have tried resetting to factory default settings for everything. even the existing Main node. I have followed every helpful hint I could find on the internet to try. Nothing works. are these devices not compatible? Pairing doesn’t work, resetting doesn’t work. I am at a loss for how I can add these new nodes. Hopefully someone can help me before I go completely crazy trying to figure this out.

Thank you,

David B.
