Client receive socket error

Hi all, we have just finish the F5 VE setup and starting with the 1st tesing and we encounter socket error on the client side

 

We were able to telnet the VS IP & Port from the client.

 

I have capture the tcpdump between client to F5 and trying to understand the handshake part.. would anyone be able to advise ?

 

Note: I have replace the Source IP = Source IP and Virtual Server IP = VS

 

Tcp dump Client to F5
