Plex iOS app with Tailscale

Hello, I have a problem with the Plex application on iPhone that does not connect to my Plex server with Tailscale.
I get a 401 error when connecting manually (authentication ?)
I tried to authorize the network of Tailscale in but unfortunately it does not work. No problem on Chrome but the interface is much less adapted to a mobile device.
My question is : which network is to be authorized without authentication on the Plex server to use it with Tailscale ?

Thanks in advance

PS: I use Tailscale because my internet connection is in 4G at home so I can’t redirect to the internet.

I’ve finally found how to do it!
