Connect to Olympe throught Skycontroller

Hello !
I am trying to connect my anafi ai drone to Olympe through the skycontroller4. I plugged my skycontroller to my computer (ubuntu 20.04) with a usbc cable. I can ping my skycontroller. Here is my code using Olympe :

import olympe
from olympe.messages.skyctrl.CoPiloting import setPilotingSource

if __name__=="__main__":
        skyctrl = olympe.SkyController("...")
        skyctrl.connect()
        skyctrl(setPilotingSource(source="Controller")).wait()
        #skyctrl.disconnect()

Here is the error i get :

[ERROR] 	ulog - pomp - connect(async)(fd=28)(addr=inet:XX:180) err=104(Connection reset by peer)

Hope you can help me with that !
