+## TUN
+
+The first time I tried to run tailscale on a Hostinger VPS, I got the following
+error: `failed to connect to local tailscaled; it doesn't appear to be running 
+(sudo systemctl start tailscaled ?)`
+
+I read something about some stuff called `TUN` on a forum, and realised that
+the VPS panel in hostinger had a switch with the title: `TUN/TAP Adapter: It's 
+a virtual network adapter that will allow you to set up a VPN on your server.
+`. I activated it (comes off by default) and that did the trick.
