Ray job submitted to Ray cluster fails to initialize, showing Failed state with error:
"Unexpected error occurred: The actor died unexpectedly before finishing this task."

Unfortunately I wasn't able to reliably reproduce this behavior. It happens occasionally when running SDK example https://github.com/project-codeflare/codeflare-sdk/blob/main/demo-notebooks/guided-demos/2_job_client.ipynb

From logs it seems to be an issue with worker node not able to connect to head node, see attachment.
