This recently started happening to me on Archlinux after a large update of packages. If I try to run any zerotier-one tool I always get:
# zerotier-one info
zerotier-one: fatal error: cannot bind to local control interface port
However, if I look at netstat output, I can see that zerotier-one is listening just fine:
# netstat -lp --numeric-ports --numeric-hosts | grep zero
tcp 0 0 127.0.0.1:9993 0.0.0.0:* LISTEN 527/zerotier-one
tcp6 0 0 ::1:9993 :::* LISTEN 527/zerotier-one
udp 0 0 10.0.0.11:45086 0.0.0.0:* 527/zerotier-one
udp 0 0 10.0.0.11:45087 0.0.0.0:* 527/zerotier-one
udp 0 0 10.0.0.11:9993 0.0.0.0:* 527/zerotier-one
Also, I can confirm that zerotier is connected, and functioning properly on this host. It doesn't matter if I restart the service or the machine, and there is no SELinux here.
Try zerotier-cli info.
Sweet mother of #$%. I'm sorry.
