ESP8266 V3 not working with Orange Cube +

I hooked up my Cube Orange + to ESP8266 V3 following the instructions at ESP8266 wifi telemetry — Copter documentation.

However, my Pixhawk 2.4.8 works just fine with the ESP8266, the MAVLink WiFi Bridge shows the packets received from the vehicle and sent to the GCS. The Mission Planner connects seamlessly with UDP at port 14550.

But when I use the same ESP8266 with my Orange Cube +, the MAVLink WiFi Bridge shows 0 packets every time.

I’ve checked the physical connection, connectors, and configuration, the firmware is updated and has no issues. My ESP32 works fine with the Orange Cube + with the Drone Bridge.
However, I can’t seem to understand the issue with the ESP8266?
