Original Pull Request: https://github.com/netbirdio/netbird/pull/6574

State: closed
Merged: Yes

Describe your changes

Wait for the signal receive watchdog to fully stop before reconnecting, so a new instance of watchdog can't flip shared stream state on the fresh connection.

Summary by CodeRabbit

Bug Fixes
- Improved shutdown reliability for the gRPC receive watchdog, ensuring it terminates cleanly when the receive stream ends.
- Updated heartbeat/probe sending to respect the active stream context, allowing in-flight probes to be cancelled promptly when the stream is cancelled.
- Further reduced chances of hanging or delayed retry behavior during disconnect and recovery.
