Original GitHub issue: https://github.com/netbirdio/netbird/issues/1736

Describe the problem
Network Routes don't work, probably because of the two Errors in the Log below. I can ping the peer Netbird IP 100.105.x.x but can't ping/access my Home Network 192.168.x.x, the Errors were there even before I created the Network Routes.

I wanted to use Netbird to get away from DS-Lite and be able to access my Network from IPv4 only Networks
Used Tailscale Years ago but now chose netbird because of the Network Route, DNS Options (I want to use my adguard home + nginx reverse proxy) and better Documentation.

To Reproduce

Steps to reproduce the behavior:

New Account on NetBird
Added a Docker Peer and my android Tablet using the Netbird App
add my home Network to Network Routes
reconnect and ping an adress from my home Network
Add home Network Router as DNS in Netbird Cloud
reconnect and ping again

Expected behavior
Access my other Services not running Netbird in my home Network by their IP

Are you using NetBird Cloud?
Yes

NetBird version
netbirdclient version 0.26.3
