"Invalid keystore format" error while configuring HTTPS on Spotfire Server

"Invalid keystore format" error while configuring HTTPS on Spotfire Server.

After configuring HTTPS on the Spotfire Server according to the Configuring HTTPS documentation, the Spotfire Server's HTTPS URL fails to load and the following error is seen in the "catalina.log" file found in the <Spotfire-Server-home>\tomcat\logs\ folder:

Caused by: java.io.IOException: Invalid keystore format

This is caused by an invalid keystore file. Check the following general steps to resolve this issue:

• This may be caused by an issue while generating the keystore. Try to regenerate the server certificate by following the steps of keystore generation, raising a CSR (Certificate Signing Request), and importing the certificate.
• Validate that the "certificateKeystoreFile" property in "server.xml" in <server installation>\tomcat\conf folder is pointing to the correct path and file.
• Validate that the "keytool.exe" path being used while generating the certificate is correct.
