Omniverse Streaming Client disconnects from remote Isaac-Sim

I am taking course Introduction to Robotic Simulations in Isaac Sim and when I make some bad mistake in Jupiter notebook, it stops and prints the following in notebook:

Execution timed out after 10 seconds. Change it via `isaac --timeout`.
Connection closed by foreign host.

And then I cannot reconnect back. It shows “An unknown error occured (0x100)” in client window.

Rerunning the following does not help

%run -i 'scripts/isaac_magic.py'
%isaac --reset --status 
Isaac call will open new connection
Logfile: Ready!
Servers: Ready!
IP Addr: 18.207.251.63

Only restarting the container helps, but it takes around 10 minutes to restart.
