WHM does not start, nor can SSH be started

My WHM does not start after restarting the server.
I can not even access the SSH "Network connection rejected"

Details of my server

I installed cpanel in a vps (VPS created by virtualizor)

My cpanel does not start automatically, every time I restart, I put the following command in ssh to restart
"iptables -F && /etc/init.d/iptables save
restart cpanel service "

For security, I have stopped ssh access from whm> General Settings and deselected SSH.

So, now my cpanel is not starting, even SSH. So I can not run my server. I have a lot of data from my clients. What can I do now?
Note: the server is running, I have checked the ping, that is work
