Describe the problem

  • I have installed netbird_0.59.12_linux_armv6.tar.gz on a Brodersen PLC (armv7l GNU/Linux) as a binary
  • I can connect to the netbird network, but after PLC reboot... netbird is down with error
  • you will see in this report how I managed to fix the issue

Log:

$ netbird status
2025-11-11T11:07:57Z INFO ./caller_not_available:0: 2025/11/11 11:07:57 WARNING: [core] [Channel #1 SubChannel #2]grpc: addrConn.createTransport failed to connect to {Addr: "/var/run/netbird.sock", ServerName: "localhost", Attributes: {"<%!p(networktype.keyType=grpc.internal.transport.networktype)>": "unix" }, BalancerAttributes: {"<%!p(pickfirstleaf.managedByPickfirstKeyType={})>": "<%!p(bool=true)>" }}. Err: connection error: desc = "transport: Error while dialing: dial unix /var/run/netbird.sock: connect: no such file or directory"

To Reproduce

Steps to reproduce the behavior:

  1. Install netbird binary armv6 as per https://docs.netbird.io/how-to/installation/linux#binary-install
  2. Connect to the netbird network - works
  3. Reboot
  4. See error - netbird did not start properly

Expected behavior

Issue should not appear. Netbird should auto-start and connect.

Are you using NetBird Cloud?

It does not matter.

NetBird version

0.59.12

Is any other VPN software installed?

No.

Debug output

To help us resolve the problem, please attach the following anonymized status output

$ netbird status -dA
2025-11-11T11:41:33Z INFO ./caller_not_available:0: 2025/11/11 11:41:33 WARNING: [core] [Channel #1 SubChannel #2]grpc: addrConn.createTransport failed to connect to {Addr: "/var/run/netbird.sock", ServerName: "localhost", Attributes: {"<%!p(networktype.keyType=grpc.internal.transport.networktype)>": "unix" }, BalancerAttributes: {"<%!p(pickfirstleaf.managedByPickfirstKeyType={})>": "<%!p(bool=true)>" }}. Err: connection error: desc = "transport: Error while dialing: dial unix /var/run/netbird.sock: connect: no such file or directory"

Screenshots

Additional context

I noticed that /etc/rc.d/S50netbird is a symlink to /etc/init.d/netbird
I modified /etc/init.d/netbird to ouput to a custom log file to see if it runs.
It did not run because it was in /etc/rc.d folder (I believe netbird service install puts it there). I then created a symlink to rc5.d instead, as I know for sure scripts in that folder run after reboot.
Now, according to my custom log file, the netbird actually runs:

Tue Nov 11 11:07:34 UTC 2025
/etc/rc5.d/S10netbird
Starting netbird
Unable to start, see /var/log/netbird/netbird.log and /var/log/netbird/netbird.err

The folder does not exist. This causes an error in the netbird script and fails.

ls: /var/log/netbird/: No such file or directory

Solution I found

  1. create symlink in /etc/rc5.d
$ sudo ln -s /etc/init.d/netbird /etc/rc5.d/S10netbird
  1. create the /var/log/netbird directory in the file '/etc/init.d/netbird'
pid_file="/var/run/$name.pid"
+ mkdir -p /var/log/netbird  
stdout_log="/var/log/netbird/$name.log"
stderr_log="/var/log/netbird/$name.err"

after reboot, voilà:

I am aware this is a very niche case. In addition as the solution works on my end, please feel free to close the ticket.

Thanks for the provided steps. Could you give us more info on what kind of operating system/distribution runs on that device?

I have converted it to a feature request and will keep it open just in case we'd want to support that setup in the future.

I think is best to check and create log folder in the script. On my laptop it seems the folder is not deleted, so maybe the PLC is removing the folder for reasons.

log_dir="/var/log/netbird"
if [ ! -d "$log_dir" ]; then
    mkdir -p "$log_dir"
fi

stdout_log="$log_dir/$name.log"
stderr_log="$log_dir/$name.err"
