Zerotier-cli shows offline, zerotier GUI shows connected

Zerotier-cli shows offline, zerotier GUI shows connected. I cannot ping other zerotier clients. It was fine last month.
I tried to install zerotier one on another PC in same network, and it shows online, but they cannot ping each other via zerotier’s IP either.

Welcome! thanks for posting.

Is this on a Windows? What version?
What does zerotier-cli listnetworks say?

Apologies for the late replay.
It is a windows server 2016 and widows 10 PC’s


I have been experiencing the same problems of late. Using Zerotier 1.4.6 on Linux daffy 5.8.9-arch2-1 #1 SMP PREEMPT Sun, 13 Sep 2020 23:44:55 +0000 x86_64 GNU/Linux

The GUI on my usual network shows that my devices are connected, yet on the zerotier-cli command it shows the network as OFFLINE (even after a stop/start/reboot)

zerotier-cli info        
200 info REDACTED 1.4.6 OFFLINE
zerotier-cli listnetworks
200 listnetworks REDACTED REDACTED REDACTED OK PRIVATE ztr2qzacab.....

As an experiment, there now, I just created a new network, did a zerotier-cli join <id> and it said:

zerotier-cli join REDACTED                
200 join OK

So it thinks it’s okay so far, but on the GUI, even after a refresh (and a wait and a refresh), it does not show the device waiting for authorization, i.e., it is saying “No devices have joined this network.”.

Doing zerotier-cli listnetworks shows:


So it’s waiting for that authentication to come through.

It seems something is not right.
