Sphinx implementation / xauth problem

Hello, I have a question about implementing sphinx
after I followed all the instruction of installing sphnix from Installation procedure - 2.8.2

I tried implementing shpnix with the code below

sudo systemctl start firmwared.service


sphinx “/opt/parrot-sphinx/usr/share/sphinx/drones/anafi_ai.drone”::firmware="ftp://:@ftp2.parrot.biz/versions/anafi2/pc/%23latest/images/anafi2-pc.ext2.zip"

and then, this error occurs

xauth: (argv):1: couldn’t query Security extension on display ":10"

for sure I got the login and pass credit number from Parrot Education education@parrot.com

I tried figuring out how to solve this but it is really hard to find the solution

please let me know how to solve this problem
