Players no longer trust certificates from emSign ECC Root CA - G3
Web pages and services whose certificates chain to emSign ECC Root CA - G3 stop loading on players running ScreenlyOS 26.10.0.
From ScreenlyOS 26.10.0, players no longer accept certificates issued under emSign ECC Root CA - G3. On October 20, 2026, keys belonging to certificate authorities under that root were found to be compromised (Mozilla bug 2083449). Players stop trusting it, for the web pages they show and for their own connections.
If this affects you: a web page on your screens whose certificate comes from emSign ECC Root CA - G3 stops loading on players running 26.10.0. Ask whoever runs the site to move to a certificate from another authority.
