Dear Mahmood,
please open a console in the VNC session, do a ssh -Y rocks7 in the
console (yes, relogin to the console) and try it again.
SLURM does not want to use local displays, and a VNC session is a
"local" display, as far as it concerns linux and the X11 subsystem.
So, you need to relogin or login to another frontend node by ssh to get
a remote display.
Best
Marcus

$DISPLAY = :1 kind of means that you are physically logged into the
machine
I am connecting through a vnc session. Right now, I have access to the
desktop of the frontend and I open a terminal and run things.
I even
xclock is working on the frontend and compute-0-0 (through ssh -Y).
