AM2434: AM243x EVM OOB Demo not working (GUI not updated)

Part Number: AM2434

Hello, 

I am trying to test the OOB Demo project on my AM243x-EVM Board.

https://dev.ti.com/gallery/view/SitaraMCU/AM243x_EVM_OOB_Experience/ver/1.0.1/

Everything seems connected and running, but the GUI is frozen with default values.

If I disconnect the board from the web browser, and check with a serial terminal, data are well received on COM6 at 115200 bauds.

I tried:

• On different web browser (Google Chrome and Edge): same result ; 
• Power-off/Power-on the EVM board: same result ; 
• Flashing again: same result.

Have I forgotten something? 

Thanks.

Regards, 

William
