X1 - Assistance adding SharePoint data source

[MustBeNice]

I'm having a hard time trying to connect a SharePoint site to X1. I haven't come across the problem before and is new to me. I haven't found an online solution yet and am finally posting my first question in the forum. I authenticate via PIV card authentication and use the "Logged-in User" X1 authentication method.

When I attempt to add this site to x1-
https://abc.sharepoint.com/sites/is/wir ... Items.aspx
I get this error: "Server was unable to process request. ---> There is no Web named "sites/is/wireless/Teams/Forms/AllItems.aspx/_vti_bin/search.asmx

https://abc.sharepoint.com/sites/is/wireless/
I get this error: "Server was unable to process request. ---> Attempted to perform an unauthorized operation.

https://abc.sharepoint.com
I get this error: "Server was unable to process request. ---> Attempted to perform an unauthorized operation.

https://abc.sharepoint.com/_vti_bin/spsearch.asmx
I get this error: "The conent type text/html; charcet=utf-8 of the response message does not match the content type of the binding (text/xml; charset=utf-8). If using a customer encoder...."

I stumbled upon the QueryService at https://abc.sharepoint/_vti_bin/spsearch.asmx. I'm not sure what to make of it. This is how it reads:

Hi,

when connecting to Sharepoint with a web browser, does the browser popup a dialog where you need to select a certificate and enter a pin?

Currently, the Sharepoint plugin in X1 does not support card authentication. We are researching ways to add that functionality for future releases.

Hi Jogy,

No, X1 never prompts to use the PIV cert to authenticate. X1 simply states "Server was unable to process request. ---> Attempted to perform an unauthorized operation." I have read access to the site, but doesn't seem to pass my logged on credentials.
