No establish connection via UDP port mavlink to edison wifi

I have a new Pixhawk2.1 hardware which I am doing the test before I installed to my hexa frame. It is flashed w/ latest apysnc.

I am struggling to connect Mission Planner via WIFI from the Edison access point (ardupilot) by following the example apysync howto video. From my available networks, I can see “ardupilot” access point- click that, enter the pw(enRouteArduPilot)- It could not establish mavlink direct connection.

But on my Android Q-Ground control apps, it is perfectly working fine! Also, serial connection by OTG is ok. I ran out of clues so I reach out the Ardupilot community for suggestion. Anyone who can help pls…thank you.
