Netbird conflicts with zScaler on a wired connection #2393

Open wsw70 opened 3 months ago

wsw70 commented 3 months ago

Describe the problem

When running netbird on a Windows 11 laptop with a wired connection, zScaler keeps restarting and netbird keeps disconnecting as well. This does not happen on a wireless connection.

To Reproduce

On a wired connection

netbird up
zScaler shortly entrers into an error mode ("internal error') and netbird keeps connecting and reconnecting (as seen with netbird status -d
netbird down restores zScaler immediately

On a wireless connection

both co-exist without any isues

Are you using NetBird Cloud?

Yes

NetBird version

0.28.6

Additional context

This is reproduced both at home (wired and wireless networks are on the same range) and in the office (where they are on distinct ranges). This is also reproduced by a friend, in the same conditions

Hello @wsw70, can you upgrade the client to 0.28.7 and run the following command on your PowerShell:

netbird -A debug -S for 1m

You can replace the 1m for the amount of minutes it takes to disconnect.

If you like, you can also join our Slack so we can have a faster feedback loop.

wsw70 commented 3 months ago

netbird -A debug -S for 1m

This fails with

PS C:\Users\y> netbird -A debug -S for 5m
Netbird up
Netbird down
Error: failed to up: create wg interface: The object already exists.

However

PS C:\Users\y> netbird up
Connected

can you upgrade the client to 0.28.7

Miracle - I cannot reproduce anymore. So my problem is gone, thanks a lot. I did not notice there was a new version available

The problem is unfortunately back (after 2 or 3 hours). The debug command this time worked and the debug bundle is attached

netbird.debug.1704977056.zip

After switching to a wireless network both Netbird and zScaler are stable (for now, but it has been like that for 2-3 days when I discovered the wired vs wireless difference)

Thanks to @lixmal there is a workaround: to disable network monitoring (see the slack thread)

netbird down
netbird up -N=false

And the problem is back again 😟 - follow-up in the slack thread
