My Zerotier Client running on a Raspberry Pi4 has been working great for over a year but after I did a full OS upgrade, now running Buster, my client shows up as OFFLINE after reboot. If I restart the service (sudo systemctl restart zerotier-one.service) it goes ONLINE immediately. Even when offline, I see the zerotier connections in “ip routes”, and “ip a”. I have tried stopping/starting the service but the issue came back after reboot. I completely uninstall Zerotier (including the keys) and reinstall but am having the same result. This is being used to remotely control a deep ocean experiment soon and I need it to be reliable. Your help would be appreciated!
Running Zerotier Version 1.12.2
