SSL handshake is not happening between client machine and F5,

on F5 we cannot see much in tcpdump capture , whats wrong in algorithm.. as we dont have visibility on client side..

 

How can we troubleshoot further?

It sounds like there might be an issue with the cipher suite you are using. I suggest referring to the AskF5 article entitled K15292: Troubleshooting SSL/TLS handshake failures for help in identifying the source of the issue.
