My wsl2 is not getting ros2 nodes from IsaacSim

[tanzimfairussakib]

I cant get my ros2 nodes on my wsl2 platform anyways.
While i installed wsl and ros2 in my windows, my windows IP and WSl2 IP was different since it was on virtual machine.
Then with Nvidia omniverse guideline, I could start IsaacSim with ros2 bridge extension in my windows 11. I did simple robot joint and added ros2 tf publisher and joint states.

After running my simulation, whenever i am going on my wsl platform, my ros2 topic list command doesnt give anything. its always
/parameter events
/rosout.

my ros2 is working since ros2 talking and listening is working. My firewall is not blocking since i tested that and ros2 nodes are open. Whatever i am doing, its not letting wsl platform to puclish any ros2 nodes.

I specified as much as I can in this post:

After sourcing it, i see /parameter_events and /rosout confirming its up and running.

Which version are you using? Could you try with 5.0?
