Hello, I have the exact same problem as yours. And somehow I solved it. Maybe this information can help you, or someone else who finds this issue.

I am using WSL2 Ubuntu 20.04, Mirrored mode networking. Here is the content of my .wslconfig:

# Settings apply across all Linux distros running on WSL 2
[wsl2]

networkingMode=mirrored
ignoredPorts=1234

On Windows, manually set the IP address to 172.31.1.50 and the subnet mask to 255.255.0.0.

On Ubuntu, execute sudo ufw allow 1234

After these configurations, rosrun kuka server_V30032017.py usually works fine. But this problem still occurs occasionally, and I don't know why.
