SSLDump

From what I could see, Version 3.1 means, its on Tls 1.1. So your client intiated handshake on tls1.1 and server (F5) also negotiates with the same. But its then failing in the changecipherspec. Definitely it hasn't gone to server-side connection yet. Its still on the client-side connection and failing. I would check on the clientssl profile ciphers and try troubleshooting.
