Originally created by @HearthCore on GitHub (Mar 16, 2025).

Describe the problem

Netbird 0.38.1 either crashes or disconnects from ProxMox Virtual Hosts and LXC containers.

To Reproduce

Update Netbird to 0.38.1 on my Starto VPS and LXCs, multiple re-installs have confirmed this.

Expected behavior

Seemless connectivity

Are you using NetBird Cloud?

Cloud

NetBird version

0.38.1

Is any other VPN software installed?

No.

Debug output

Can't provide. Production environment compliance.

Screenshots

Nothing to "see" other than the Peer leaving and joining in the Cloud console.

Additional context

I have the same issues on a Windows DELL XPS15, a Virtual ProxMox Host, Debian LXCs and on Premises Baremetal ProxMox Hosts aswell.

Have you tried these troubleshooting steps?

  • Checked for newer NetBird versions
  • Searched for similar issues on GitHub (including closed ones)
  • Restarted the NetBird client
  • Disabled other VPN software
  • Checked firewall settings

Solution
Revert the Update or downgrade to 0.38.0 which seems to run without issues.
For Debian: apt install netbird=0.38.0

Seeing the same issue here on both Windows and Linux clients.
Downgraded back to 0.38.0 and everything is fine now.
