Zerotier-cli: missing port and zerotier-one.port not found in /var/lib/zerotier-one

Hello everybody,

I started to setup zerotier and have a network with one client.
now I try to add another armbian buster Rock Chip 3399 System to add and installed the zerotier-one (1.6.5).
zerotier-one/buster,now 1.6.5 arm64 [installed]
but when I run “sudo zerotier-one info” I am getting the message “zerotier-one: fatal error: cannot bind to local control interface port 9993”
if I run “sudo zerotier-cli info” I am getting that error message “zerotier-cli: missing port and zerotier-one.port not found in /var/lib/zerotier-one”

The 127.0.0.1 and the IP@ of that unit are both listening to 9993
The file zerotier-one.port is not in /var/lib/zerotier-one.

Any ideas or even a solution for my problem?

thanks
