is TLS 1.3 is supported on F5 OS version 9.4

I have a small testing application running behind F5. However, from Firefox/Internet explorer I am able to access the webpage but not from Edge and Chrome browsers. 

The virtual server is enabled with an SSL client profile and a valid certificate is imported and the Server SSL profile is also enabled as default. 

When I enabled debugging mode on the browser, I can see F5 working on TLS 1, and the backend server is using TLS 1.3

F5 Running OS Version 9.4.2

is TLS 1.3 is supported by 9.4 Version.

    Hi Jaspreetgurm,

    quoting from K10251520: "In BIG-IP 14.0.0, the BIG-IP system adds limited support for Transport Layer Security (TLS) 1.3. Starting in BIG-IP 14.1.0.1 and later, this support was updated to provide production level support for TLS 1.3."  

    But BIG-IP 9.4... That is end of software development, end of technical support, end of everything.
    Please consider upgrading to 14.1 minimum. Better 15.1 or 16.1.
