Ooh, thank you absolute newbie, for asking something here that even I can answer! :wink:

Someone has a firewall turned on. Such things bounce all TCP/IP from (deep breath) external subnet classes with suspicious port numbers, such as 4100.

Firewalls typically freely permit 80, and might sometimes permit 8080 or 8000. Further, some web serving OSs only let people with super-user permissions listen on port 80.

So change one of your ports, or add 4100 as a trusted custom port on your firewall, and you are set.
