When creating an http connection type, if the connection page is not the default and you change the port from the default of 80 to something else, the url that gets passed to the browser is incorrect. For example, if you configure the Hostname/IP field with something in the form of nodename/login_page and set the port to 8080, the url passed to the browser is http:
nodename/login_page:8080, which fails, instead of the correct http:
I found a workaround by leaving the port set to the default of 80, and putting nodename:8080/login_page in the Hostname/IP field, which generates the correct url.
