avahi-autoipd link-local conflicts with zerotier interfaces
Yet another cause of netscript/routing failures, if avahi-daemon is running with the default bionic config it will break routing, although you can't see this until the interfaces are brought up:
root@arm:~# route

And in the fpnd.log you can see this with VERBOSE enabled:
