Just a quick PSA: be careful when updating Tailscale arbitrarily as it can break. I suggest sticking with the version available with whatever package manager bundles for your firmware build. In the 7.17.x track, you can get up to 1.86.2 which is fairly recent.
See RutOS firmware 7.17.x + Tailscale (any post-1.70 version) = broken for more…
