Wiki: The hostname HttpSys the server channel should listen on. The default value is ‘*’, which means that the server channel receives all requests, regardless of hostname.
If I do this, when starting the server I get a single dialog stating Access Denied (in dutch), and the server is terminated.
Many names are denied for the hostname, also for nonstandard ports like 9503. Turning off the firewall does not help.
localhost is accepted, but nothing else… But if I fill in localhost, remote connections are not accepted, because of an invalid hostname.
Sounds like an access restriction on the windows account running the server. His channel uses the kernel-level http.sys driver, I’m not surprised that Windows restricts non-admin, non-system accounts from registering with that; this would also explain when"localhost" works.
