    maybe you have missed some configuration for ssl proxy feature , I understood from Pcap snapshot that F5 could not validate destination server certificate to pass it to the client , so as a result of this error in ssl sequance ( Specially regarding to ssl Proxy deployments ) F5 send RST packets to close ssl connection , so I see that F5 Resets the destination server (First RST)  and the client as well ( Second RST ).

    For that reason , Please follow this KB well to configure and build  ssl proxy correctly :
