Hello, I have installed and configured the Tailscale add-on and I can access my HA correctly from other devices in my Tailnet using SSL with it’s MagicDNS name (ex. https://homeassistant.my-tailnet.ts.net). All good there.
My trouble is trying to access other devices on the Tailnet from HA using their MagicDNS names (ex. https://jellyfin.my-tailnet.ts.net). I have disabled the userspace_networking config and I can access other devices in the Tailnet using only by their IP address, but if I try to ping using the MagicDNS name I get this error: ping: bad address 'jellyfin.my-tailnet.ts.net'
In the Tailscale add-on documentation it says:
To be able to address those clients not only with their tailnet IP, but with their tailnet name, you have to configure Home Assistant’s DNS options also.
I don’t know what DNS configuration I need to do here.
Any help would be appreciated 
Tailscale config:
advertise_exit_node: false
advertise_connector: false
advertise_routes: []
log_level: debug
proxy: true
