Routes/DNS entries missing after client updates

[roberthase]

Problem after updating windows clients to 0.35.2 and the following versions up to 0.36.3:

Clients can connect to the controller but routes and dns entries in the local regristry get deleted right after creation.

Restarting or disconnecting/connecting or updating/reinstalling the client do not help.

To resolve this issue, clients have to be deleted in the controller and readded.
Other reports from my colleagues indicate that deleting and readding the group of the peer in the controller can also help resolve this.

Self hosted controller version 0.36.3
Clients are added with setup-keys.

We have about 500 devices running netbird and so far 1-2% of all devices seems to be affected, when we roll out updates.
