Can't connects XenCenter with XenServer

Question

I am trying to connect XenCenter 6.0 to Server installed with XENSERVER 6.0 but i can't connect.
It give me error when i try to connect :

"Unable to connect to server '192.xxx.xxx.xxx'.
The connection was refused.
Check that Xenserver is configured correctly on '192.xxx.xxx.xxx'."

Also When i was using another computer for connecting xencenter, It was disconnecting automatically every time i connect

Answer 1

Examine some details:

1. List item
2. the server is power-on
3. the network configuration is right.(try to use "ping" or "ssh" to check)
4. the firewall setting
5. duplicate IP address which has been used

Answer 2

There are two possible scenarios in this case .

Either 1. The xenserver physical machine is powered off. Or 2. The network cable is not connected properly.

Answer 3

If the server is pingable, make sure xapi and xapi-ssl are running.

ssh to the xen server and check the following:

/etc/init.d/xapi status /etc/init.d/xapi-ssl status

If they are not running restart them /etc/init.d/xapi start /etc/init.d/xapi-ssl start

might require a xe-toolstack-restart
