On the desktop where the HTML Access Agent is installed, start the Windows Registry Editor. Again, servers can enforce only latest TLS 1.2 protocol on the server for enhancing server security. Similarly, TLS 1.2 and lower cipher suites cannot be used with TLS 1.3 (IETF TLS 1.3 draft 21). You may notice that many large corporate sites also display this warning due to an old cipher method the server is using. Before you create and deploy a custom cipher group (that is, the final cipher string for SSL negotiation), you can review the pre-built cipher groups on the BIG-IP system to see if any of them already contains the cipher suites you need.
