I added a new SSL/TLS certificate to the web site, but it only fixes the web pages access using HTTPS: and does not work for the app file access (game versions <9.8.7 don’t work). I will continue to work on this problem. Probably need a more flexible (wildcard) SSL certificate. The app does not need HTTPS: encrypted access so you can fix the app/game problem by updating to the latest version, 9.8.7, when it is available. 9.8.7 has been submitted for review and approval by Apple and Google. 9.8.7 is available for Windows, by downloading from the web page. The older versions should still work on the web because the web game does not access the server files. I have not updated Linux, but do not know of anyone using our app on Linux.
