Hi @Neeraj Kumar ,
As mentioned in this official Azure document, it is not necessary to create a pull server for Azure Automation State Configuration as it provides a built-in pull server.
On the other hand, it looks to be similar to this question. Please review it for more information and see if it helps. If this doesn't help then please share more details like OS of your virtual machine, your config file, few screenshots of your setup if possible, etc. so I can try to reproduce with the same set of things in my lab and get back to you with additional insights.
