Browser support for TLS 1.0 and 1.1 has ended
The four major browsers no longer support Transport Layer Security (TLS) 1.0 and 1.1.
What you need to know
This change doesn't affect your DigiCert certificates. Your certificates continue to work as they always have.
This change affects browser-dependent services and applications relying on TLS 1.0 or 1.1. Now that browser support for TLS 1.0 and 1.1 has ended, any out-of-date systems will be unable to make HTTPS connections.
What you need to do
If you are affected by this change and your system supports more recent versions of the TLS protocol, upgrade your server configuration as soon as you can to TLS 1.2 or TLS 1.3.
If you do not upgrade to TLS 1.2 or 1.3, your webserver, system, or agent will not be able to use HTTPS to securely communicate with the certificate.
