Zerotier-cli listnetworks shows no network on certain Proxmox CT

hi,
I have 2 Proxmox CT, one is ubuntu 22.04 based and the other is debian. I have configured those two using zerotier-cli to access remotely.

But one of the CT shows no network connected when I type zerotier-cli listnetworks
This CT is also enabled in my Zerotier dashboard for that network.
I can’t connect to this CT from remote.

The Ubuntu based one:

root@immich:~# zerotier-cli join xxxxxxxxxxx903cd
200 join OK

root@immich:~# zerotier-cli listnetworks
200 listnetworks <nwid> <name> <mac> <status> <type> <dev> <ZT assigned ips>
root@immich:~#

The other CT (Debian) shows network connections when I type zerotier-cli listnetworks and I can connect to the IP of this CT from remote.

root@nextcloud:~# zerotier-cli join xxxxxxxxxxx903cd
200 join OK

root@nextcloud:~# zerotier-cli listnetworks
200 listnetworks <nwid> <name> <mac> <status> <type> <dev> <ZT assigned ips>
200 listnetworks xxxxxxxxxxx903cd homelab xx:yy:aa:bb:11:22 OK PRIVATE zbcoh5m2al xx.xxx.xx.55/24
root@nextcloud:~#

The pve itself is connected to zerotier without problem. I can remote management my proxmox. But I want to be able to access my not-connected CT through IP address…

How can I resolve this issue?

Thank you

I had the exact same error on in CT Debian 12 on Proxmox 8.1.4. I found a hay solution that worked for me. I didn’t follow all the steps, only points 2, 3, 4 and then just reloaded Zerotier.

apparently, I just need to do point number 2! and it works
