Routes disappear after short time

[xan-it]

Describe the problem

We use selfhosted netbird installation. We have one PC that is behaving strangely: After connecting to netbird, all the routes (or the one we select with the UI) are available and listed by the command "route print". We can ping private IPs from the remote site. After a while (<5 min) the routes disappear in the "route print" command and we can't ping the IPs anymore. After a restart of the netbird service the routes reappear for the next short period. A "netbird status -d" shows all remote peers as connected.

To Reproduce

Steps to reproduce the behavior:

1. connecting to netbird
2. use command "route print" to see network routes
3. do a "ping -t" to an IP on the remote site
4. after a while the ping does not work anymore
5. check with "route print". The routes are disappeared

Expected behavior

the routes should not disappear after a while.

Are you using NetBird Cloud?

@xan-it can you test with 0.28.9 version? Here is the link for the installer: https://github.com/netbirdio/netbird/releases/download/v0.28.8/netbird_installer_0.28.8_windows_amd64.exe

HI @xan-it,

could you test the latest release https://github.com/netbirdio/netbird/releases/tag/v0.31.1 please? If the issue still occurs:

• please provide the log file, e.g. through netbird debug bundle -A (the attached logs are irrelevant to the observed issue).
• is there anything on the system that could have deleted the routes?
