}
}
}
ltm virtual https_example_vs {
destination 192.168.1.155:https
ip-protocol tcp
mask 255.255.255.255
pool srv1_https_pool
profiles {
http { }
tcp { }
}
snat automap

}

HTTP profiles are incompatible with encrypted pass-through traffic, such as SSL and require a Client SSL profile to decrypt the traffic for L7 HTTP inspection. If the virtual server processing the encrypted traffic is configured with an HTTP profile and no Client SSL profile, the connection fails.

D is correct, it should require also SSL profile. Not sure why removing the HTTP profile worked, but tested this in a Lab and D is correct..

sorry D is correct. Adding client Client SSL Profile will not fix the problem since you still need Server SSL Profile. But removing the Http profile will fix the problem
