Original GitHub issue: https://github.com/netbirdio/netbird/issues/5107

Describe the problem

Basically, if netbird starts before there is (public) internet access, it stops retrying to login after about a minute.

We are using netbird on a nixos-based PC, which is part of a small setup, connected to it's own router. We first encountered this issue when there was a power loss, and the PC booted up faster than the router it was connected to. The router is a bit slow, but it seems that it only connects to the public internet after the netbird service stops trying to connect. We were running v0.43.3, but the same problem occurs with v0.62.1.

I came upon this issue: https://github.com/netbirdio/netbird/issues/1361 but it doesn't seem to be the same situation, as that seems to be about clients that were already connection, which then lose connection.

To Reproduce

Steps to reproduce the behavior:

  1. Disconnect your system from public internet
  2. Start netbird
  3. Wait for a bit more than a minute
  4. The systemd logs will read something like

  1. If you now reconnect your device to the internet, netbird will not try to login anymore, the service will still be running but your client will not connect.

Expected behavior

This doesn't seem to be configurable, but my expected behavior is one of the following:

  • The systemd service crashes, allowing us to retry through systemd
  • Netbird will keep trying to reconnect

Are you using NetBird Cloud?

Yes

NetBird version

v0.43.3 and also v0.62.1

Is any other VPN software installed?

No

I can't run netbird status -dA:

Daemon status: LoginFailed

Run UP command to log in with SSO (interactive login):

 netbird up 

If you are running a self-hosted version and no SSO provider has been configured in your Management Server,
you can use a setup-key:

 netbird up --management-url <YOUR_MANAGEMENT_URL> --setup-key <YOUR_SETUP_KEY>

More info: https://docs.netbird.io/how-to/register-machines-using-setup-keys

Additional context

We are running on nixos 25.05, using the package as available in nixpkgs.

Have you tried these troubleshooting steps?

  • Reviewed client troubleshooting (if applicable)
  • Checked for newer NetBird versions
  • Searched for similar issues on GitHub (including closed ones)
  • Restarted the NetBird client (well, restarting it would make it work as it is then connected to the public internet)
  • Disabled other VPN software
  • Checked firewall settings
Originally created by @DenSinH on GitHub (Jan 15, 2026). Original GitHub issue: https://github.com/netbirdio/netbird/issues/5107 **Describe the problem** Basically, if netbird starts before there is (public) internet access, it stops retrying to login after about a minute. We are using netbird on a nixos-based PC, which is part of a small setup, connected to it's own router. We first encountered this issue when there was a power loss, and the PC booted up faster than the router it was connected to. The router is a bit slow, but it seems that it only connects to the public internet _after_ the netbird service stops trying to connect. We were running v0.43.3, but the same problem occurs with v0.62.1. I came upon this issue: https://github.com/netbirdio/netbird/issues/1361 but it doesn't seem to be the same situation, as that seems to be about clients that were already connection, which then lose connection. **To Reproduce** Steps to reproduce the behavior: 1. Disconnect your system from public internet 2. Start netbird 3. Wait for a bit more than a minute 4. The systemd logs will read something like ``` Jan 15 10:06:08 sf6-control netbird[1105]: 2026-01-15T10:06:08Z ERRO util/grpc/dialer.go:45: Failed to dial: d.Dialer.DialContext: dial tcp: lookup api.netbird.io: no such host Jan 15 10:06:08 sf6-control netbird[1105]: 2026-01-15T10:06:08Z INFO ./caller_not_available:0: 2026/01/15 10:06:08 WARNING: [core] [Channel #8 SubChannel #9]grpc: addrConn.createTransport failed to connect to {Addr: "api.netbird.io:443", ServerName: "api.netbird.io:443", }.

If you now reconnect your device to the internet, netbird will _not_ try to login anymore, the service will still be running but your client will not connect. **Expected behavior** This doesn't seem to be configurable, but my expected behavior is one of the following: - The systemd service crashes, allowing us to retry through systemd - Netbird will keep trying to reconnect **Are you using NetBird Cloud?** Yes **NetBird version** `v0.43.3` and also `v0.62.1` **Is any other VPN software installed?** No **Debug output** ``` Jan 15 10:05:37 sf6-control systemd[1]: Starting A WireGuard-based mesh network that connects your devices into a single private network...

same problem here.

I am running client-version 0.64.5 on my windows 11 Machine and Server Version 0.65.2 on my selfhosted VPS-Server.

Right now, the issue doesn't occur on any of my linux server/clients. Only Windows-Client have this issue

I updated to the latest selfhosted version 0.65.3 and downloaded the netbrd client from the webUI. Before I installed netbird-client via chochlatey. This time "netbird up" brought a sign in message:

I am running nextcloud since several Months, maybe even 2 Years without this error. I connected many Windows Client/Servers, Linux Clients/Servers and even Synology NAS-System with it wouth any issue. Did something change in the config, that I am not aware of?
