vncserver vnc client "Failed To Connect: Connection Refused (10061)"

I'm receiving the error "Failed To Connect: Connection Refused (10061)".

This error normally indicates that an endpoint was reached by the connection attempt (so some kind of host/computer) but that no service was running on that port and so the connection was refused.
Common causes of this problem are:

1. That the service is not running
2. That the service is not running on the port you contacted
3. That the internal IP of the VNC Server has changed, invalidating the port-forward rule in the router

Linux节点远程vnc访问报错，后来发现是防火墙的原因。
关闭防火墙服务：service iptables stop
