Can’t ping or access devices on a Zerotier VPN

 After rebooting, you may find you cannot ping or access another of your Zerotier hosts on your VPN eg by SSH. 

 

 

The solution to this is as follows:

 

On both machines that cant access or ping each other, run the following to find their Zerotier ID

 

sudo zerotier-cli info

 

eg

 

200 info **999xxxxx99** 1.6.2 ONLINE

 

Then, on each machine stop the zerotier service:

 

sudo systemctl stop zerotier-one

 

Next, delete the peer data for each machine on both machines:

 

eg in this case:

 

sudo rm /var/lib/zerotier-one/peers.d/999xxxxx99.peer

 

Then, having done that – on both machines that have the problem, restart the zerotier service:

 

sudo systemctl start zerotier-one

 

both machines should now be reachable in both directions via your Zerotier VPN.
