@Ameer_Haj_Ali Yeah that would be really great, I am really concerned about this as the research is completely paused and I am so desperate for the results as this is very important in my career and this is a medical research and this will help in research progress. @Alex can you please help me with it ? we can program it together to fix the issue. Anytime would work for me tomorrow that is monday 06/06/2022. But I am in London so please let me know your availability along with the time zone you are in so I can schedule accordingly. Thank you. ---

Hi @sohail_4233, did you fix your issue? I’ve met the same issue when creating a cluster of two windows 10 using version 1.13. I’m wondering if there is any preliminary requirement before setup a cluster, e.g., make network sharing? If it is, how can I do that? Anything I need to do for the firewall? ---

@Yuhang_Zhang windows multi-node support is experimental. Would you mind posting a Ray GitHub bug report detailing the issues you encountered? ---

Hi @Yuhang_Zhang , the issue was not resolved. it is not the setup required it is just that ray only works well with linux and mac OS. I have tried a lot with windows but it does not work at all.
