Attendant Console Error- Unable to connect to server

[Mojo1]

The Attendant Console client used to work. I have made no changes to the setting but says unable to connect to server. I can ping the server.

What would the problem be?

It may be that your TCD service has quit responding. Restart TCD. I have seen TCD just lock up many times.

Its under your control panel in call manager.

This is from memory so it may not be 100% accurate.

Call Manager Servicability----tools---control center

Restart Telephony Call Dispatch on both servers.
