If a "netstat -nlp" shows nothing on that port, then it seems the
issue is that nothing is actually listening on that port. Trying to
figure out what might be blocking the port is asking the wrong
question - the port may not be blocked at all. But it doesn't look
like whatever service you think should be listening on that port is
actually doing so. You need to figure out why the service is either
not starting up, or not listening on the port you think it's
supposed to be on. Check the logs for that service, and turn up the
verbosity of its output if necessary (and possible).<br>
