My PC is not getting its IP configuration

Hi,
I use Zerotier on 12 devices since 4 years.

Since 2 hours, ZeroTier is not working on my Laptop.
I uninstalled then reinstalled.
I rebooted the PC.
I checked the network setting (the windows feature).
I didn’t change anything on the computer.
Everything seems ok.

The client is connecting well, but there is no IP configuration.

the network interface is getting an autoconfiguration IP ( 192.168.157.57 ) and not the IP from my ZeroTier network.

My all other devices are working well (Android, Rasperry Pi, a windows PC, …).

Please, do you have any idea?
Is it possible that ZEROTIER servers have a currently a problem, not giving the IP settings?
Thank you.

In Windows, the ZeroTier network interface has IPv4 configuration set to manual but empty, where my second Windows PC has an IP from the ZeroTier network.

On the first, I can manually set the IP, then it’s working. But if I disconnect the ZeroTier client then reconnect, the IP configuration is again empty.

Please, anyone has an idea?

Really, nobody could help ?

Did you Authorize both of them?

Autorize what ?

One Zerotier client is not anymore giving the IP configuration (it was working well since 4 years)

I suspect that same issue happens to my Android 1.14.0-2 client.
I have tried to remove the joint network and re-join, but there is no device shows up in the network center which I can manage authorization. So it does not work now.

I find out what happened now.
I have switch my phone from Google Pixel 7 to Google Pixel 9 using Android’s automatic backup.
And it reuse all the old config from the old phone.
I thought I need to delete the old Pixel 7 from member to let Pixel 9 rejoin fresh. And I did so, that is why Pixel 9 does not work.
Now I have restored the deleted member and it works.

Please ?

Since you can manually give it an IP in Windows, Zerotier seems to (mostly) be working. It’s just the auto assign IP that isn’t working correctly.

Open command prompt as admin, run this command and tell us what the result is:

zerotier-cli get <your network id> allowManaged

Thank you :slight_smile:
The résult is : 0
Only this.

Cool, that’s likely your problem then. In the command prompt, type:

zerotier-cli set <your network id> allowManaged=1
14

After few seconds, I got a long “answer” with a lot of parameters.

I will try soon as possible (I can’t stop the network / reboot the PC currently).

Thank you :slight_smile:

Yes, that’s what you should see. In that list, you’ll see something like this:

{"allowDNS":false,"allowDefault":false,"allowGlobal":false,"allowManaged":true

The "allowManaged":true is the important part. If that’s set, you should then be able to have an IP assigned to the interface.

I confirm, it’s on TRUE.

Do you have any idea why it “broke” like that ?
I didn’t change anything around ZeroTier.

In the system tray, there’s a place to set that. You might have accidentally deselected it. Outside of that, it’s hard to say. Could be a bug, or a version update changed it.
