This error indicates that the TIBCO Spotfire Statistics Services server (TSSS) URL (seen as "<myTSSS_URL>" in the example error above) is either:

• Incorrect or invalid.
• Is inaccessible from the Web Player or Node Manager machine.

To resolve:

• Verify that the TSSS server URL is a valid URL and is correct for your TIBCO Spotfire Statistics Services installation. For example, validate the URL by successfully opening that URL in a browser on the TSSS machine itself or on a different machine. 
• Verify that the TSSS server URL is accessible from the Web Player / Node Manager machine directly. For example, by logging into the Web Player / Node Manager machine and successfully opening that URL in a browser.

The TSSS server URL is set in the preferences, accessible via:

• TIBCO Spotfire Analyst client > Tools > Preferences > <Group Name> > TIBCO Spotfire Statistics Services > Statistics Services

After modifying the preference, you must log out and log back in so that the new preference value will be registered. Additionally, if you have the preferences defined on multiple groups, ensure all are correct and that you understand the inheritance and precedence, as per the referenced KB article 000022058.

See the documentation reference for detailed instructions. When entering the TSSS URLs, ensure there are no extra spaces, special characters, or other typing errors. Documentation: Configuring TIBCO Spotfire to use TIBCO Spotfire Statistics Services
