trouble to access nlb

Hi

 

I've configure BIG-IP LTM according to your video training, I've also create an NLB for two of my web servers when I'm trying to acess to the NLB by web I'm getting TLS error ("turn on tls 1.0 tls 1.1 and tls 1.2 in advanced settings") TLS is on and I suspenct that one of my configuration is wrong

 

please advice

 

Thanks, Idan.
