To resolve, ensure to update the <certificateKeystorePassword> attribute with the correct password in the server.xml file located at "<TIBCO Spotfire server installation directory>\tomcat\conf" folder.
Alternatively, you can perform the following to test the password:
- In Windows, double click on the .pfx file
- Select "Next" until you are asked to enter a password
- Check if the password is correct and matches the one in server.xml
If Windows will not accept the password then the TIBCO Spotfire Server will not either.
