I thought I would post a fix for an error I'm sure people are having. This is a proper fix for "Unable to start webserver" on Kodi startup. This fix should work for Kodi 16.* where the webserver not running because the address is in use. Apparently "happy cast" listens on the ip interface *.*.*.*:8080. That means all ip addresses on port 8080. Consequently, Kodi cannot listen on that port as well.
To verify this from a console: "netstat -anp | grep 8080"...
