Is this a feature you had working previously, or has it never worked at all?
If it is new functionality, I'd start here: https://one.workfront.com/s/document-item?bundleId=workfront-classic&topicId=Content%2FReports_and_D...
It is possible that your Jira administrator disallows this type of connection, and you would have to work with them to allow it.
Thanks for your reply. i saw that link already before submitting the question - but honestly I'm not able to find out the correct way to get this done.
I tried with 2 or 3 web links (like JIRA or other news article) to paste into WF dashboard, but everything gives same error.
Has someone successfully done JIRA report or dashboard into a Workfront dashboard?
