Xiaomi Gate Way - error getting token - devices online

So I’ve just got a new gateway.

I’ve added it via manual things The dev key I think I have right. The Serial number I can only see one in the app, an 8 digit number.

Bridge mihome:bridge:9999999 "Xiaomi Gateway" [ serialNumber="9999999", ipAddress="192.168.100.23", port=9898, key="mykey", pollingInterval=6000 ] {
    Thing mihome:gateway:9999999"Xiaomi Mi Smart Home Gateway" [itemId="9999999"]
}

It my serial number, the bridge id number and the item id of the gateway all suuposed to be the same 8 digit number? As for me they are.

I can’t seem to automatically find…but that will be network. I run a Ubiquiti USG, and their APs also. I’ve put this device on an IOT network, but have allowed port 9898 both ways in udp. And the ip address of the gateway is what in in the thing definition. Openhab is running on a different subnet, but there is routing between the two.

Both the bridge and gateway show as online.

But when switching a light I see the following:

Any ideas? Do I have one of the values wrong?
