Check your connection
Confirm your device is really connected, read its addresses and reach a server by its device name.
After running the connection command, you can check two places: the device itself and the panel. The commands are the same on macOS, Windows and Linux and only read status; they don't need sudo.
Check on the device
tailscale statusThe first line shows your own device, its address starting with 100. and its state. The lines below are the other devices you can reach.
To print just your own address:
tailscale ip -4Addresses on the network come from 100.64.0.0/10; every device also gets an IPv6 address starting with fd7a:.
Check in the panel
In Devices on the network page, confirm your device shows as Online. The list doesn't refresh on its own: click Refresh to see a newly connected device.
Reach another device
If a rule grants you access to the device you want, you can reach it in two ways:
By address
Use the address starting with
100.fromtailscale status, for examplessh [email protected].By device name
You can also reach devices on your nixscale network by name. The full name works everywhere and looks like
<device>.<network-id>.net.nixscale.com, for examplessh [email protected]. If your operating system applies the search domain, the short name (ssh user@office-gateway) works too. Device names appear in thetailscale statusoutput.
To test connectivity (if the rules allow ICMP):
ping 100.112.0.2On macOS and Linux, stop ping with Ctrl + C.
Reading the results
| What you see | What it means | What to do |
|---|---|---|
tailscale status prints your device and its address | The device is connected | Nothing to do |
| The output says "Logged out." | The connection was never made, or the device was signed out | Get a new key from the panel and connect |
| No devices besides your own | There may be no rule | Ask your network admin for access |
A device is listed but ping gets no reply | The rules may not allow ICMP, or the target device is off | Ask an admin to check the rule |
| The device isn't in the panel | The list may be stale | Click Refresh |
If the problem continues: I can't connect.
