Connection to Google BigQuery may fail to connect due to the installed version of .Net Framework on the Node Manager Server

Details:

When an analysis / Dashboard is opened that requires connection to Google BigQuery data, sometimes the user may see this message:

Then if they click Skip or Cancel, they get an Analysis window that is mostly blank except this message: "Not logged into the external connection".

This failure might be occurring due to the version of .Net Framework that the Node Manager (NM) service is using. This scenario correlates to the following log file entry: "The certificate key algorithm is not supported."

Solution: 

A possible solution is to install a newer version of Microsoft .Net Framework on your NM server. For example, if your NM server belonging to an v11.4 Spotfire server is using .Net Framework 4.5.2, then upgrade to .Net Framework 4.8 and then reboot your NM server.

Following is an example entry of an nm.log file, which indicates the version of .Net Framework that the service is using:
