Spotfire Node Manager: Nodes fail with "Certificate for .. doesn't match any subject alternate..."

This article addresses the issue where the nodes fail to start with the following error. 

The reason for this error is that during the node manager installation an incorrect supervisor name (hostname for the spotfire server) was chosen.

The spotfire cluster uses internal hostnames for inter node communication. These should not be confused with the public hostname (or URL) used for the spotfire cluster. The public URL is how end users will connect to the application

E.g. https://spotfire.example.com for end user access vs spotfire1.example.com as an internal hostname of the spotfire server (i.e the machine hostname)

If the incorrect supervisor name is chosen during the install, the node will eventually fail to come online with an error similar to the above. 

To resolve the issue, edit the [Node Install]\nm\config\nodemanager.properties file as follows:

Change the server.name to be the correct internal hostname of the spotfire server. This can be seen in the Nodes and Servicies view of the web console.

server.name=spotfire1

Note: The hostname provided must be resolvable via DNS (or at least via a hosts entry in the system hosts file)

Restart the node manager service and the node should them come online. If this still fails consider uninstalling the node manager software and starting over.
