Video Stream is not Viewable With VPN (or AdGuard Pro) Enabled
Hey there. I'm not entirely sure if this issue is fixable, but I wanted to report it anyways. I have the latest version of the Ring plugin (9.18.1), and it works great! My Ring 2 (battery powered) shows up as it should in my Home app on my iPhone, I am able to see snapshots when having the room open that I placed the Ring into, and I am able to view the livestream without trouble.

However, whenever I try to enable any form of VPN (or the AdGuard Pro DNS that creates a "VPN" connection on my iPhone), I no longer am able to view the livestream from the Doorbell. When I try, it spins and eventually goes to the "No Response, This camera is not responding" error. The logs from Homebridge are identical when I am attempting to connect without a VPN vs with a VPN (with the exception that attempting to connect with a VPN eventually returns the inactive message as shown below):

> [6/7/2021, 9:57:34 AM] [Ring] Preparing Live Stream for Front Door
[6/7/2021, 9:57:35 AM] [Ring] Waiting for stream data from Front Door (0.575s)

This is consistent behavior, every time I have my VPN (or AdGuard DNS blocking) enabled, the Doorbell live feed will not show, and every time I have them disabled, it will show. I do not believe this is resulting from AdGuard DNS blocking specific requests, as I attempted to whitelist every domain that was blocked while opening the stream, and the behavior did not change (also, my actual VPN does not attempt to block requests, and the behavior still occurs when this is turned on and AdGuard is disabled).
