Homebridge Ring Plugin: Unable to Subscribe to Events - 406 Not Acceptable Error from Ring API

[BardiaZadeh]

Is there an existing issue for this?

• I have searched the existing issues

Describe The Bug

The Homebridge Ring Plugin fails to subscribe to events (e.g., motion or ding events) for my Ring device. The log reports repeated 406 Not Acceptable errors from the Ring API, and the session hardware ID is missing. The plugin retries creating a new session, but it still fails with the same error.

To Reproduce

1.	Install and configure the Homebridge Ring Plugin.
2.	Run.
3.	Check the logs for errors.

Expected behavior

The plugin should successfully subscribe to events (e.g., motion or ding events) for my Ring device and receive updates without errors.

VPS server from Ionos

Note that it is not just subscriptions that are failing, there are also 406 error on calls to basic device enumeration API endpoints. If you search this error in the issues you will find other similar reports by users running on various VPS services. It seems to be that Ring bans connections from most IP blocks on those cheap hosting services, likely because most of those services are used heavily for various nefarious reasons and there's no legitimate reason that any official Ring API consumer would come from those IP blocks. Honestly, I'm struggling to come up with a reason to run Homebridge on such a server, but regardless, it is not possible to use the Ring plugin from these servers and such use is not supported.
