Well in most cases when it fails we run a netstat and find that it is not listening for some reason, either the user disabled it or uninstalled it. But this is a case where they confirmed one of the listed ports shows listening on a netstat command so we are baffled as to why it says it failed when trying to connect. Maybe the failure is something more complicated and we want to see what failed exactly. If you just visit the page it says failed with no information so we need something like a button we can press to connect and watch it attempt to talk to the service with more detail.
