About centos7 use zerotier problem

[g670677773]

I installed and used zerotier on centos7, but when I run zerotier-one -d, it tells me “zerotier-one: fatal error: cannot bind to local control interface port”
When I use the “zerotier-cli status” command to check the status, it tells me that I am offline, but I have allowed this device in my backend

zerotier-one: fatal error: cannot bind to local control interface port

That means ZeroTier is already running

When I use the “zerotier-cli status” command to check the status, it tells me that I am offline, but I have allowed this device in my backend

firewalld is enabled by default on Centos 7. It may be blocking ZeroTier from communicating.
