Can't start IsaacLab after deploying at AWS with Automator

[1g0rrr]

Hi!
I want to run Isaac Lab simulation on AWS g4dn.x2large (Tesla T4) but got errors. What can cause it?

Case 1:
But when I try to start IsaacLab inside isaac lab container with this command:
./isaaclab.sh -p source/standalone/tutorials/03_envs/create_quadruped_base_env.py
I got error "Error] [omni.appwindow.plugin] Failed to acquire IWindowing interface" and then script stops

Case 2
When I try to start Isaac Sim in it's container with this command:
./isaacsim.sh
I got similar error, but log go further:

Case 3
When I try to start headless Isaac Sim in 'isaac-shell.sh' container with this command
./runheadless.native.sh
all seems ok.

Specs:

GPU: g4dn.x2large (Tesla T4)
Isaac Sim Version: 4.0.0

Full log of Case 1:

I also have the same problem.
my gpu is g5.2xlarge (the default)
I get the Iwindowing error when running from ssh, and it gets stuck when connected with novnc.
it works when running with --headless

[guyostfeld]

new update for me, managed to run the isaac sim, I recommend using NoMachine since it's the fastest way to connect and waiting for a few minutes after opening isaac-sim or running a training. just ignore the not responding error

@1g0rrr @guyostfeld thanks, we're looking into this
