Screenful integration with JIRA - getting authorization error while creating Dashboards

[arpita.prajapati]

I am trying to create a new Dashboard in the Screenful App for JIRA.

However it is giving me Access Issue and the dropdown for existing Boards is not getting populated. I have created one Board and was able to do this earlier. Not sure how to fix this problem now. I have the Screenful account created and am logged in. Any pointers on the issue?

The AUTHORIZE YOUR TOOL tab is giving message - "No found. Please check your access rights."  And the dropdown is not populated.
