wa aleikum assalam bro,
seems like you server has failed to start successfully, check out your server status, you should see something like this:
Cisco 7200 Simulation Platform (version 0.2.6-RC5-x86)

Hypervisor TCP control server started (port 7200).
if it didn't show this message then there's something preventing the server from starting properly, it might be your firewalls, try to desactivate all your firewalls and run it again..
I hope it'll work
