It looks like a client issue - the client is querying Netbios to determine the netbios name prior to issuing the client hello. You may need to create another virtual to forward the Netbios request to the pool member server so that the client receives a netbios response and the SSL negotiation can start.

 

Check your ACE to see it it was able to pass the Netbios request through to the pool member.

 

Or find out why the client is issuing the Netbios request, and maybe disable that feature.
