I meant change port 8080 to 433 of course.
443... man I hate this "you can't edit your posts" policy! ;)
Did you ever manage to get this sorted out? We are experiencing the same issue.
We have an F5 load balancer but the WSDL which gets returned always shows the direct address of one of the cluster nodes instead of the url for the F5 :(
Thus, the only part that is being load balanced is retrieval of the WSDL !!
You say you solved the problem with the domain name, so you might have the answer :)
