Having issue, when trying to use HTTP secure-channel instead of HTTP

Our Flex application uses LCDS(we are using ColdFusion8 that has integrated LCDS) to proxy Web Service, it works fine if I am using HTTP non-secure channel.

We changed proxy-config.xml to define destination that uses non-secure channel as follows:

<?xml version="1.0" encoding="UTF-8"?>
<service id="proxy-service"
    class="flex.messaging.services.HTTPProxyService"
    messageTypes="flex.messaging.messages.HTTPMessage,flex.messaging.messages.SOAPMessage">

    <properties>
        <connection-manager>
            <max-total-connections>100</max-total-connections>
            <default-max-connections-per-host>2</default-max-connections-per-host>
        </connection-manager>
        <allow-lax-ssl>true</allow-lax-ssl>
    </properties>

    <adapters>
        <adapter-definition id="http-proxy" class="flex.messaging.services.http.HTTPProxyAdapter" default="true"/>
        <adapter-definition id="soap-proxy" class="flex.messaging.services.http.SOAPProxyAdapter"/>
    </adapters>

    <default-channels>
        <channel ref="java-http"/>

    </default-channels>

   <destination id="SomeService">
       <properties>
           <wsdl>http://eng.com:8080/webservices/SomeService.wsdl</wsdl>
           <soap>http://eng.com:8080/webservices/</soap>
           <remote-username>suser</remote-username>
           <remote-password>password</remote-password>
       </properties>
       <adapter ref="soap-proxy"/>
   </destination>

</service>

To use secure HTTP channel, we canhged the following elements in proxy-config.xml

<default-channels>
         <channel ref="java-secure-http"/>

</default-channels>

<destination id="SomeService">
        <properties>
            <wsdl>https://eng.com/webservices/SomeService.wsdl</wsdl>
            <soap>https://eng.com/webservices/</soap>
            <remote-username>suser</remote-username>
            <remote-password>password</remote-password>
        </properties>
        <adapter ref="soap-proxy"/>
    </destination>

When I am trying to use proxy-config.xml with secure HTTP channel defintion, connection to the WebService failed with an error: "Can't load WSDL. Check WSDL url".  Any help or suggestions what we are doing wrong?

Thanks in advance
