When you try to connect to a SharePoint list through OData in Tableau Desktop 8.1, one of the following errors might occur:
You do not have permissions from the OData source to access the data. Check with the data provider to obtain or update your permissions.
Your request might have been denied because your account exceeded the quota for this resource.
Service unavailable. Check to make sure the service is running.
Internet communication error: SSL connect error <server name>
- Tableau Desktop 8.1
- Microsoft SharePoint
Disabling libcurl and enabling WinINet might allow you to connect. Use the following workaround:
On the Windows Start menu, click Run, type regedit, and then click OK.
In the Registry Editor, navigate to HKEY_CURRENT_USER > Software > Tableau > Tableau 8.1 > Settings.
Right-click Settings, and select New > String Value.
Name the new string value LegacyHttpClientEnabled.
Right-click LegacyHttpClientEnabled and select Modify.
In Value data, type true, and then click OK.
Tableau Desktop 8.0 uses WinINet to handle HTTP requests, whereas Tableau Desktop 8.1 uses libcurl.
