401 error for any command, trying to run on Ubuntu

Hi,
New to Linux and zerotier.

I’m running Ubuntu 18.04.5 LTS.

When installing zerotier, and trying to connect to an already-created network (sudo zerotier-cli join [network ID]) or run any other zerotier command in the Ubuntu terminal, I get a 401 error.

e.g. 401 join {}
or $ sudo zerotier-cli status
401 status {}

Anyone have any ideas as to what I’m doing wrong here?

I’ve tried

  • Uninstall /reinstall
  • Install different methods - install is “successful” but still 401 error
  • Rebooted machine

I’ve googled a good bit, few with the same problem, and not getting anywhere with it.

Any help appreciated.

Is there a file .zeroTierOneAuthToken In your home directory? If so delete it. If that fails or doesn’t exist, remove /var/lib/zerotier-one/authtoken.secret and restart the zerotier service and try again.

Thanks for quick response.

  1. Any idea where I would fine those files from the Terminal? (is it below output?) sorry, a novice.

  2. And how to delete them / how to restart the zerotier service from Terminal?

$ sudo ./ZeroTierOne/
artwork/ debian/ .git/ java/ rule-compiler/
attic/ doc/ .github/ macui/ service/
controller/ dockerbuild/ .gitignore node/ update_controllers.sh
cycle_controllers.sh ext/ include/ osdep/ windows/

Did you install with the script from https://www.zerotier.com/download/ ?

It looks like you’re looking at the source code which you users don’t generally need.
