Tailscale breaks Airplay music streaming on LAN


I just installed Tailscale on my Synology NAS and since then Synology Audio Station (music player) cannot stream to Airplay (Apple or emulated) devices anymore.
As soon as I stop the Tailscale app then music resumes.
N.B. I’m talking about devices on same LAN, not on remote Tailnet.

Thank you.
