With all the new updates to browsers' codebase for security and the previous discontinuing of SSL in favor of TLS certificates, the self-signed certificates created by Linkstation 200 series is now broken on most Google Chrome/Chromium, Microsoft Edge and other webkit codebase browsers. Mozilla browsers continue to allow it with warnings.
This is such a basic update but there is no way to manually do it without command line access. Additionally, the easiest way to do it is install Certbot aka 'Let's Encrypt' which is a clean package install and just works and it's FREE!!!!!!
If you have a workaround or a hack. Let's hear it.
