I have just updated to 1.2.1-t9446e5c17 on both my Synology NAS.
Everything has been working fine, but all of a sudden, we haft lost connectivity with one of the NAS.
The admin page says last seen “less than a minute ago”
But I’m unable to connect to it, over the Tailscale network, from my other NAS, and from other clients, on different networks, on both Linux and Mac. Both is latest version.
Any good idea ?
