Whitebear 2.5 ERROR HTTP/1.1 Service Unavailable

I've run Whitebear for a while and normally it works great. But sometimes it fails after a few weeks. On the first tab both Logitech and Whitebear server status are green and "running" but on the Whitebear's Status page all items have a "-" but the IP address that has a red message ERROR HTTP/1.1 Service Unavailable

The odd thing is that restarting Whitebear and or Squeezeserver does not help. I need to reboot the whole machine. Very odd.

Anyone have any idea what to do?
