Netbird >0.40 disconnects after some time.

[xromansx]

Now I'm running on version 0.41.3 but from version 0.36 netbird routing peer disconnects from server when in inactive state and for some reason reporting different client versions in logs.

[sleb23]

I'm also getting reports of these disconnections. For info's sake, reported users were on client version 0.39.2. After upgrading to 0.43.0, disconnections have stopped.

**Edit: Btw, I think you mean <0.40 (less than) disconnects, right @xromansx ?

[xromansx]

I think it is related to openwrt 24.10.1 on 23 version no problems.

[pscriptos]

Has anyone fixed the problem yet?

I have the same problem, also still in version 0.46.0

Hello Folks, if you still facing this issue, can you please share a debug bundle?

Hello Folks, if you still facing this issue, can you please share a debug bundle?

Thank you very much for your feedback.

Do you need anything else from me?

[mlsmaycon]

actually, if it happens every few minutes, can you run this command instead?:

netbird debug for 1m --system-info --upload-bundle -A

Adjust the 1m if it takes more than 1 minute for the peers to reconnect.

Also, can you confirm the peer NetBird IP that is reconnecting? that will help us focus on specific log events

[pscriptos]

The current issue is that the Netbird client with the IP address 100.83.12.99 (vps02-docker01) should establish a connection to my server network. This usually happens by using a gateway. The gateway has the IP address 100.83.229.208 (vhost02) in the Netbird network.

Initially, it helped if I briefly deactivated the resources and then reactivated them. Unfortunately, this no longer works today.

I have just deactivated and reactivated a resource (server network) while creating the logs
I hope all this helps you.
If there is anything else I can do, please let me know.

I’d like to mention that we’re experiencing a similar issue: after some time—typically more than a month—the Netbird service needs to be restarted for new peers to successfully connect. Existing connections continue to work fine, but newly connecting peers fail to establish a connection with the routers.
We’re running the latest version (59.x).
I have another setup running an older version of Netbird (0.32.x), and I’ve never encountered this issue there.

When peers can not connect, it seems that they are not able to get the ice candidate endpoints:

 ip-10-110-1-130-38-228.netbird.selfhosted:
  NetBird IP: 100.127.38.228
  Status: Connecting
  -- detail --
  Connection type: -
  ICE candidate (Local/Remote): -/-
  ICE candidate endpoints (Local/Remote): -/-
  Relay server address: 
  Last connection update: 3 minutes, 31 seconds ago
  Last WireGuard handshake: -
  Transfer status (received/sent) 0 B/0 B
  Quantum resistance: false
  Networks: -
  Latency: 0s

Is netbird retrying to get again ice candidates when it is not able to find them in P2P connections ?
A netbird service restart solves the issue.

Would it be possible to add a new feature in netbird dashboard, to trigger a netbird service restart of a peer?
