Zerotier - PORT_ERROR on MacOS

I am connected to the network, but I can't get an IP address because of the PORT_ERROR:

$ zerotier-cli join f00ba7abcdf00ba7
200 join OK

$ sudo zerotier-cli status
200 info abcd123123 1.2.12 ONLINE

$ zerotier-cli listnetworks
200 listnetworks <nwid> <name> <mac> <status> <type> <dev> <ZT assigned ips>
200 listnetworks f00ba7abcdf00ba7  1e:12:34:56:30:86 PORT_ERROR PRIVATE  -
Solution

  • Zerotier installs a custom kernel extension to the system. Starting from MacOS 10.13 (High Sierra), you have only 30 minutes to approve this kext.

    So, the solution is:

    1. Uninstall zerotier:

      sudo "/Library/Application Support/ZeroTier/One/uninstall.sh"

    2. Install zerotier again:

      https://zerotier.com/download/

    3. Open "System Preferences", then go to "Security and Privacy" -> "General" -> Click "Allow" at the bottom of the window.

    4. Done! Now you can get an IP address. Don't forget to authorize the device in ZeroTier Central.
