This seems to be a long running issue with versions 4, 5, and 6 and I have not seen a decent answer beyond check your firewall. It would be nice if we knew which address/port the application was attempting to connect to for troubleshooting purposes.
Hello Presonus?
Update: Digging a little deeper on this, it appears that the version of TLS on Windows 7 is not compatible with the version that api.presonus.com is expecting. Or, rather, requiring.
For Windows 7 you will need to upgrade to TLS v1.2 as per this Knowledgebase article -
