I can't connect yuzu to UDP server

Hi all
I managed to make wiimotehook work on linux with wine,

Found another valid Wiimote: #3 Querying...
Battery level: 0.00 %.
Turning on LED #: 3 and rumbling for a moment
Extensions: None
Motion mode set to: DS3
Setting up the key binds configuration...
Launching XInput emulation..
The gamepads emulation driver was not found; continuing without XInput support
Shaking: Update 10ms / Speed 500 / Pressing 100ms
Starting the motion server on IP:port 127.0.0.1:26760:
UDP server listening

Keys: [O: Motion Orientation] [D: D-pad Orientation] [Q: Exit]
      [S: Settings Editor] [H: Hide to Tray] [L: Open the Log]

but when i test the server on yuzu settings it says: Unable to receive valid data from server.
Please verify that the server is correctly configured and that the address and port are correct.
on windows when I launch wiimotehook, the test with yuzu succeeded directly
am i doing something wrong ??thanks

In order for us to provide better support, we need to see the log generated by yuzu. This guide will walk you through how you can obtain the log file: Getting Log Files - yuzu

Install the driver needed for xinput emulation. It’s usually called vigem driver. Since it’s using the default config it should work out of the box. Unless you are running in a vm or something.

thank you
it is already done ViGEmBusSetup_x86.msi,
i am on ubuntu 20.04
