Same issue here. I did previously have the Fling for host client installed on these hosts, so that may be an issue.
Web UI message:
503 Service Unavailable (Failed to connect to endpoint: [N7Vmacore4Http16LocalServiceSpecE:0x1f0daf08] _serverNamespace = /ui _isRedirect = false _port = 8308)

Thoughts?
