Hi-
We've built an internal Data Portal using the Hub framework. I'm trying to provide the ability to search our portal for documents as well as all of the spatial data. We have loads of documents in our Sharepoint site that I'd like to be able to provide to our staff as links when they search our internal portal. For example, when our staff searches the internal portal for "Prairie Dogs", I'd like them to not only get the spatial data that is titled and/or tagged "Prairie Dogs", but also documents on Sharepoint related to Prairie Dogs. I've gone ahead and created AGOL items for these documents that are links to PDFs or Word Docs in Sharepoint, and these work just fine. But when I share the AGOL item with the content group for our internal data portal, I get this error message (cityofboulder.sharepoint.com refused to connect.):

Any ideas?
Thanks in advance!
Jennifer
