Describe the problem

I have two peers:

  • bs19: 100.81.178.217 (Ubuntu 24.04, netbird version 0.51.1)
  • andrei: 100.81.83.4 (MacOS, netbird version 0.37.1)

Issues:

  • I can ping from bs19 to peer to andrei peer.
  • I can't ping from andrei peer to bs19 peer.

I trying to check all last versions.

  • 0.51.1 - not working
  • 0.50.0 - not working
  • 0.49.0 - working
  • 0.48.0 - working

So, I guess, there is some regress bug, deployed in 0.50.0 version of the NetBird. As a temporary solution, I downgrade NetBird client to 0.49.0, but please check the latest version.

Have you tried these troubleshooting steps?

  • Reviewed client troubleshooting (if applicable)

  • Restarted the NetBird client
  • Disabled other VPN software
  • Checked firewall settings

Could you gather debug bundles from both latest working and first broken versions while trying to ping peers? Please attach which peers are you pinging with which bundle.

you can prepare the bundle with netbird bundle for 1m -SU (non-anonymized)

Same error, I had to downgrade to 0.50.3 in all linux machines. I got the "Required key not available" error while pinging machines outside local network

Confirm the same behavior on Linux clients with pinging outside local network, installing version 0.50.3 solves the issue.

0.51.2 works fine for me! I had issues with 0.51.1 yesterday.

Hi @mlsmaycon,

I have updated one machine from 0.50.3 to 0.51.2, again can not ping remote netbird client machine, can ping only machines within local network.

@Gdenich could you please share the bundle upload key from the following command?

netbird debug for 1m --upload-bundle

And the node you or IP you are trying to ping?

For selfhosted folks, have you upgraded the relay container to the latest image? See the requirement here https://github.com/netbirdio/netbird/releases/tag/v0.51.0
