Cisco Unity Connection web inbox giving HTTP error 500

I am trying to load balance the web inbox of Cisco Unity connection. I get the login page and can login, then once I try hitting the web inbox link, I get the following error:

Unable to retrieve spec for http://cisco-vm.stjude.org/inbox/gadgets/msg/msg-gadget.xml. HTTP error 500

When I hit the server directly instead of using the VS, it works fine.

I'm trying to use one FQN to get to multiple services, hence the use of my iRule. Config below:

    ltm virtual redirect_cisco-vm.stjude.org_http {
    destination 10.200.44.43:http
    ip-protocol tcp
    mask 255.255.255.255
    profiles {
        http { }
        tcp { }
    }
    rules {
        _sys_https_redirect
    }
    source 0.0.0.0/0
    vs-index 6
}

ltm virtual vs_cisco-vm.stjude.org_https {
    destination 10.200.44.43:https
    ip-protocol tcp
    mask 255.255.255.255
    persist {
        cookie {
            default yes
        }
    }
    pool cisco-vm.stjude.org_https_pool
    profiles {

        http { }
        serverssl {
            context serverside
        }
        tcp { }
    }
    rules {
        ciscopca_temp
    }
    source 0.0.0.0/0

ltm rule ciscopca_temp {

    if { [string tolower [HTTP::uri]] eq "/"} {
        HTTP::redirect "/ciscopca"
    }
