Version mismatch - I'm not a smart man

So I realized the other day that my exit node wasn't working anymore. Wasn't thinking that when I nuked my raspberry pi, obviously my tailscale install would stop working.

Fixed that.

Let me preface this - I am not a smart man - most of this isn't in my wheelhouse . . .

Anyways, I tried to update tailscale on my Ugreen NAS via SSH and was was having some issues where I eventually just unistalled Tailscale.

Well, upon reinstall, when I run sudo tailscale up, I get the version mismatch warning:

Warning: client version "1.102.3-t9329c3677-ga522f65e9" != tailscaled server version "1.96.2-td916d8651-gd905b0868"

I've uninstalled and reinstalled and I can't get this to work.

What am I doing wrong? Any help is appreciated!
