Hi,
Sir,If you are unable to load panel then make sure virtualizor service is running which can be checked using :#service virtualizor status
If it is stopped then you will need to start the service
#service virtualizor start
If you use service virtualizor restart command then virtualizor will ping 4.2.2.1 . So if ping is disabled on your server then you can try starting php, nginx and mysql service separately :
/usr/local/emps/bin/fpmctl start
/usr/local/emps/bin/nginxctl start
/usr/local/emps/bin/mysqlctl start
*Firewall
Virtualizor uses ports from 4081 - 4085. If there is any firewall restricting this, you will need to allow these ports.
For RHEL & CentOS < 7
iptables -I INPUT 1 -p tcp -m tcp --dport 4081:4085 -j ACCEPT
iptables -I INPUT 2 -p tcp -m tcp --dport 5900:6000 -j ACCEPT
For RHEL & CentOS 7+
firewall-cmd --zone=public --permanent --add-port=4081-4085/tcp
firewall-cmd --zone=public --permanent --add-port=5900-6000/tcp
