Hi @amr5 

1) proxy message is likely because you have access to internet thru a proxy. Please check CubeProgrammer documentation to setup a proxy (there is a menu in 'Help -> Proxy settings)

2) no DFU is not normal.

- Did you connect the right USB to the board (it is not the STLINK one) ?

- Did the board in DFU mode (check BOOT pins)

Regards.
