+Be aware that using a Zigbee Coordinator via a Serial-Proxy-Server (also known as Serial-to-IP bridge or Ser2Net remote adapter) over a Wi-Fi, WAN, or VPN connection is not recommended.
+
+Serial protocols used by the Zigbee Coordinator do not have enough robustness, resilience, or fault tolerance to handle packet loss and latency delays that can occur over unstable connections.
+
+A Zigbee Coordinator requires a stable local connection to its serial port interface with no drops in communication between it and the Zigbee gateway application running on the host computer.

+#### NCP entered failed state
+
+When you see `NCP entered failed state. Requesting APP controller restart` in logs during normal operation, it indicates a drop in communication between ZHA and the serial interface of the Silabs EmberZNet Zigbee Coordinator.
+
+The EZSP (EmberZNet Serial Protocol) interface used by Silicon Labs EmberZNet Zigbee Coordinator adapters requires a stable connection to the serial port; therefore, it is not recommended to use a connection over Wi-Fi, WAN, VPN, etc.
