On-Premise Gateway works with SQL Server, does not work with SharePoint 2013

(0) ShareShare

Posted on by Microsoft Employee

I have the on-premise gateway running and it works with PowerApps and PowerBI to connect to an on-premise SQL Server.

 

However, whenever I to connect to our SharePoint 2013 on-premise system, I enter the URL of the site that has the list I want to get to and I get:

 

We couldn't access your data. Please check the address or try again.

 

One or more of your connections may not be authenticated. Please go to the connections menu to fix them.

I have tried several different URLs of sites on our SharePoint server, including the root site.

 

I am certain I am entering the correct password for the user I am specifying. I have tried entering it has user@mydomain.com and mydomain\user.

 

The user does have access - it is my login and I am a farm admin.

 

What could be causing the problem? I saw another post with a similar problem and there was no resolution.

    Hi @Anonymous,

     

     

    Are your SharePoint on-premises web application is configured on HTTPS only?

    Yes... and no.

     

    I am not entirely an expert on the network side of things, but what I think is the case is that the Kemp reverse proxy/load balancer presents the SharePoint URLs as https, and the certificates are installed on the Kemp proxy/load balancer.

     

    But internally in IIS, the web applications think they are on http. The Kemp does the translation to http.

     

    Everyone, internal and external, uses an https URL. However, in IIS, the web applications are running on port 80. The SharePoint Alternate Access Mappings map http to https as the public URL.

     

    In a browser, if I type "http://myportal.mydomain.com", it will redirect to "https://myportal.mydomain.com". I cannot access SharePoint via http.
