Outline URL link not working

I created left nav. as a outline. I am using URL option as a type in “Data element” button in outline. My value under Data element is “https://register.clinicalt.gov/prs/html/results_definitions.html”.

From notes client when I click on data element button I get this

The requested document (URL https://register.clinicalt.gov/prs/html/results_definitions.html) could not be accessed.

The remote server either is not accessible or is refusing to serve the document.

Notes 6.5 worked fine this start after upgrade to 8.0.1

please advise
