Unable to find JIRA Board

I had created a JIRA Board with https://arkenstone.atlassian.net/, which I am unable to retrieve

Hi @SHASHIKUMAR VISHWAKARMA ,

Suggested approach here would be to reach out to your Jira admin, as those users can view all configurations and items (incl. hidden/private boards). Simply follow these instructions to change permissions.

Note that this is a public forum, mostly consisting of Atlassian end users and partners, so we cannot help out with this. 

Cheers,
Tobi
