Hi @Prakash Chandra welcome to the community.  There's an active incident with Atlassian and Confluence at the moment.  You can check out the status here: Atlassian Status 

You can investigate that to see if it's your issue. 

If that isn't it, or if you would like some confirmation from Atlassian Support, as you have a license to Cloud Premium, I would suggest opening a ticket with them at support.atlassian.com/contact and they can help you further..

They would also be able to confirm if your issue is based on the Atlassian Incident or not.
