Sorry for late reply. I was not allowed to post another reply for 22 hours.

@ [jordanm](/u/jordanm) Not sure what you mean with VPN interface?

But the Pi has a virtual interface with an ip address assigned from Zerotier. Local ip address on eth0 is 192.168.178.36. The ip address on the virtual interface is 10.147.17.36. And I have access to the machine through VPN, just not to grafana.
