I have a very particular problem
I have the client running on 1 pc inside a private network. this PC/docker container provides access to the network for other clients. In particular a mail relay server on a VPS.

If for any reason I restart the container on the pc on the network the external hosts cannot access until I restart the client on their side.

To Reproduce

Steps to reproduce the behavior:

  1. Have a network exposed by a netbird client on a docker image
  2. Have a client on a different network that can access the first through netbird
  3. Restart the container
  4. Client loses connection to the network until restarted

Expected behavior

Client keep working

Are you using NetBird Cloud?

Netbird Cloud

NetBird version
netbird version
0.45.1
Linux both.

Is any other VPN software installed?
No

If yes, which one?

@allancomar we've released a fix in 0.45.2 that might help with the behavior you are seeing. Can you upgrade your client and routing peer?
