We are aware of an issue that some customers are seeing when trying to download NGS CORS base station files through Trimble Positions Desktop. Downloads will fail with an error message that says “Could not create SSL/TLS secure channel” in the log. We are in communication with NGS regarding recent changes and intend to provide a workaround within the next 24 hours. In the meantime, you can always download base station files manually (using the links in the log file) and create a profile for a local folder where you will store them.
Check back here soon for more information.
