I'm using Airtime 2.5.1 for over a year and the listener stats always worked but the last month it got stuck. I tried everything but as far as I know it should work, but it doesn't. So I hope someone is able to help me with this problem. I've made some screenshots from my Airtime so you can check everything in order to help me better.
Well as it says in your screenshot, the password (admin password) for the stream is wrong (this is not the airtime admin password but the icecast/shoutcast password)
This is the password that you use to login to the administration in the shoutcast web page that according to your screenshot should be http://s5.pilovali.nl:8000/
