Original Pull Request: https://github.com/netbirdio/netbird/pull/5553

State: closed
Merged: Yes

Describe your changes

TrayOpenedCh is not implemented in the systray library on Windows, so exit nodes were never refreshed after the initial connect. Combined with the management sync not having populated routes yet when the Connected status fires, this caused the exit node menu to remain empty permanently after disconnect/reconnect cycles.

Add a background poller on Windows that refreshes exit nodes while connected, with fast initial polling to catch routes from management sync followed by a steady 10s interval. On macOS/Linux, TrayOpenedCh continues to handle refreshes on each tray open.

Also fix a data race on connectClient assignment in the server's connect() method and add nil checks in CleanState/DeleteState to prevent panics when connectClient is nil.

Summary by CodeRabbit

Bug Fixes
- Prevented nil-pointer issues by guarding connection state checks
- Ensured cleanup clears connection state safely and cancels exit-node retries on disconnect
- Improved concurrent access safety for connection client
New Features
- OS-aware exit-node refresh with optimized polling and more reliable menu refresh
- Safer connection initialization and assignment flow
Tests
- Added tests covering connection synchronization, concurrent access, nil/edge cases, and exit-node refresh behavior
