If your root server is unreachable, go through the following steps:
1. Check the status in the customer panel:
Log in and check whether the server is shown as "Online". If it is stopped, start it from the panel.
2. Restart the server:
Use the "Restart" function in the customer panel. For serious problems, perform a hard reset.
3. Use VNC/the console:
The VNC console in the customer panel gives you direct access to the server – even when SSH or RDP isn't working.
4. Check the firewall:
A firewall rule may be blocking access. Using the VNC console, you can temporarily disable the firewall:sudo ufw disable (UFW)sudo iptables -P INPUT ACCEPT followed by sudo iptables -F (iptables)
Important: iptables -F only deletes the rules, not the default policy. If the policy is set to DROP, the server will no longer be reachable over the network at all after flushing – so always set the policy to ACCEPT first.
5. Disk full?
A full disk can cause problems. Check the disk space:df -h
If the problem persists, open a support ticket with a description of the error.
