Hi @diwanjim,
Looks like the “Send to Tableau Server” node cannot verify the SSL certificate of your Tableau server. If you access the Tableau Server from your browser does the browser show that the connection is secure? (If it is not secure you should contact your administrator to set up a valid SSL certificate)
If the connection is secure you can add the certificate to the JVM manually as explained in this post: Tableau Hyper, send to tableau server.
Best,
Benjamin
