Howdy, your code isn't actually passing the ssl_opts parameter to the LWP::UserAgent. This will work though:

my $client = RPC::XML::Client->new("https://10.40.1.114/api/index.ice"
+,
                useragent => [
                        ssl_opts => {
                                verify_hostname => 0,
                                SSL_verify_mode => SSL_VERIFY_NONE,
                        },
                ],
);
