Unable to add Ring accessories to HomeKit but correctly showing in Homebridge Logs
# Bug Report

### Describe the Bug
For some time my ring devices have been showing as 'unavailable' in the Apple Home app. Today I decided to delete the child bridge they were connected with which removed all of the devices from my Home app. I also deleted the plugin from my Homebridge that runs on a Raspberry Pi, updated the Homebridge version and the Node.js version (now running 16.16.0).

I installed the Ring plugin and went through the setup steps and restarted the Homebridge. When it restarted I see the devices in the logs (see below log copy and past) but i don't see any devices on the 'Accessories' page in the Homebridge UI.

I followed the troubleshooting guides to restart my phone, homebridge server etc but it didn't change. I have the Ring plugin running on a Child bridge - when I scan the QR code for that I get an error saying that it's an uncertified accessory - I choose add anyway and the 'connecting to bridge' eventually times out and says unable to add accessory.

I tried also without turning on the Child Bridge option and still the devices don't appear in the Home app on my phone.

I checked and my phone is connected via wi-fi to the same router as my Raspberry Pi that is connected via Eithernet to the same router's LAN port.


### To Reproduce
Steps to reproduce the behavior:
 - Start Homebridge
 - Turn on child bridge mode on the Homebridge Ring plug in
 - Scan the QR code and choose 'Add Anyway' when the uncertified accessory error
 - Connecting to bridge times out

### Expected behavior
I expected that the devices would appear in my Home app running on iOS (iPhone) once I scanned the QR code.
