Multiple plugins hitting EHOSTUNREACH errors

Describe Your Problem: I have Homebridge installed on a Raspberry Pi 3. Recently I started seeing multiple plugins hitting the same EHOSTUNREACH errors which is impacting their functionality.

Troubleshooting steps taken:

1. Restarting my Homebridge server multiple times
2. Restarting my routers (Eero Pro)
3. Assigning a static IP address to Homebridge
4. Disabling some of the Eero experimental features (e.g. Local DNS caching)

Unfortunately none of the steps appear to have made a difference and I am still seeing the same errors.

The HomeKit Accessory Security feature could be the main issue. Have you turned off restrictions for the Homebridge/Raspberry Pi devices?

I think you might be right! As soon as I turned off HomeKit Accessory Security the errors went away. I am going to try re-enabling the feature now but with Homebridge set to “No Restriction”. Reading over the way this feature works, I can totally see how it could have caused the problems I was seeing. Apple probably has no clue what services Homebridge is capable of talking to and as a result ends up blocking various legitimate connections.
