I think I tracked this down. Seems users experiencing this issue have an invalid copy of the local API authorization token
macOS fix:
- Close the ZeroTier tray application
- Open a terminal and execute the following command:
rm ~/Library/Application\ Support/ZeroTier/One/authtoken.secret
and possiblyrm ~/Library/Application\ Support/ZeroTier/authtoken.secret
as well - Reopen the ZeroTier UI application. You should be prompted for the administrator password so you can re-copy the authtoken into your user settings folder.
Windows:
- Open Explorer and type:
%LOCALAPPDATA%\ZeroTier\
into the location bar. - Remove
authtoken.secret
. - If a
One
subfolder exists, deleteauthtoken.secret
from there as well.
