unable to connect to hw_server

Question

this is my first attempt to program an FPGA (I use Basys 3), and when I tried to connect to the hw_server after generating the bitstream , I got this error: 

Quote

ERROR: [Labtools 27-2223] Unable to connect to hw_server with URL "TCP:localhost:3121".
Resolution: 1. Check the host name, port number and network connectivity.
2. Check to ensure the hw_server is running on the target.

hello, i have the same problem... my laptop can't see the board even it doesn't appear in the ports com section when I connect it... I try to reinstall the drivers but I can't do it because windows tells that i am not an admin... someone have any idea to fix it? I try with different USB cables but I think that I need the drivers or my Arty A7 doesn't work fine...

Hi Enrique,

If you don't have the correct drivers, different USB cables won't help.

When you open Vivado do a right click on the icon and select Run As Administrator and then try again to call the path.

If it doesn't work, contact the person who administrates your computer to install the drivers. If it's your personal computer, try to enable the administrator account from Computer Management.  

Regards,

Bianca
