WHM does not start, SSH can not be started either

My WHM does not start after rebooting the server.
Also I can not access the SSH "network connection refused"

Details about my server

I installed cpanel on a vps (VPS was created by virtualizor)

My cpanel does not start automatically. At each reboot, I set the following command in ssh to restart the computer
"iptables -F && /etc/init.d/iptables save
Service Cpanel Restart "

For security reasons, I disabled SSH access from Whm> General Settings and SSH.

Now my Cpanel does not start, not even SSH. SO I can not run my server. I have a lot of data from my clients. What can I do now?
Note: Server is running, I've checked the ping that works
