No response timeout

[bwalls]

I have a Mi-Light iBox 1 that used to work great with homebridge. It still works to control all the light strips through the iPhone app, but it no longer responds to homebridge. I have the correct IP address, and can access the hub's web front end through a browser. But in the homebridge log, I see:

[28/01/2023, 15:39:35] Loaded plugin: [email protected]

[28/01/2023, 15:39:49] [MiLight] [192.168.1.131] no response timeout

and when I try to control one of the lights in the Home app, I get:

[28/01/2023, 16:48:08] [MiLight] [bridge] Setting power state to on
[28/01/2023, 16:48:08] [MiLight] [bridge] Setting brightness to 44

My relevant config is as follows:
{
"platform": "MiLight",
"name": "MiLight",
"bridges": [
{
"ip_address": "192.168.1.131",
"version": "v6",
"lights": {
"rgbw": [
"TV Backlight",
"Deck Main",
"Deck Side",
"iMac Backlight"
],
"bridge": [
"bridge"
]
},
"repeat": 3,
"delay": 100
}
]
},

and I tried setting the port to 8899. Any hints to make it work again?
