Unable to target another VIP or Pool

If the VIP is starting to LB to servers on port 443 then there would need to be a server side SSL profile. If you only have the client side SSL profile it will decrypt the traffic and that will work for the 80 pool members but then when it switches to the 443 members, they will be expecting encrypted traffic but will be receiving decrypted traffic.

Hope that helps! If it does please up-vote and select this answer, it'd be greatly appreciated!
