I/o timeout error for syncthing over tailscale


I set up Syncthing and it runs over my local network.
I added Tailscale and it works great for just about everything…
Except for Syncthing.
The error I get is i/o timeout.
Please, what went wrong?

My guess would be that SyncThing on the remote node isn’t listening on the tailscale network interface. Users do report success using Syncthing over Tailscale, so it can definitely work.

At around the time that Syncthing times out, collecting a bugreport from both nodes would be helpful. From Linux this is “tailscale bugreport”, from Windows one pushes shift while clicking on the taskbar icon and selecting Debug > Bug report, on macOS hold option while clicking on the menubar icon and select Debug > Bug report.
