Routes/DNS entries missing after client updates

[roberthase]

Problem after updating windows clients to 0.35.2 and the following versions up to 0.36.3:

Clients can connect to the controller but routes and dns entries in the local regristry get deleted right after creation.

Restarting or disconnecting/connecting or updating/reinstalling the client do not help.

To resolve this issue, clients have to be deleted in the controller and readded.
Other reports from my colleagues indicate that deleting and readding the group of the peer in the controller can also help resolve this.

Self hosted controller version 0.36.3
Clients are added with setup-keys.

We have about 500 devices running netbird and so far 1-2% of all devices seems to be affected, when we roll out updates.

Hi @roberthase,

what does netbird status -dA look like on an affected device? The debug bundle would also be helpful, at least the network_map.json from the archive.

netbird debug for 1m -AS

Hi @lixmal

here is the netbird status -dA output. The ip-adress of the local interface seems off. Is netbird using the wrong interface/route for the wireguard tunnel?

After fixing it, it show the correct local-ip of our branch network.

To follow up on the issue, which is still affecting multiple devices a day:

When running netbird status --detail on a broken device - ice candidate endpoints local is the same ip as my controller.
When running netbird status --detail on a working device - ice candidate endpoints local is the ip of the local lan/wlan interface.

Moving a peer out of the group and into the group fixes this issue immidiatly.

Seems to be the same as #3121
