Sorry for the late reply.
Could you tell me your software version of your module(you can execute: ATI) and a detailed description of your problem?

Warning: The server may listen on any port it chooses, but if it chooses any port other than 80 or 443, it may have problems with firewalls and/or proxies.
So use 80
