Hello @Niral Dave ,
Thanks for the question and using MS Q&A platform.
Let me start that the repository link which you shared is not Microsoft owned and so it's best to reach out to the owner of the repository for clarification.
On reading the document it looks like the owner did spin some Azure resources and then later is turn it down and so you are getting the timeout error.
