What to Do When Your Server Is Unreachable

Immediate Steps

1. Verify from multiple locations — try a different network, use your phone data, or ask a colleague
2. Check provider status page — there may be a known outage
3. Try alternative access — VNC console if available (Kazepute portal has VNC access)

Network Diagnostics (From Another Machine)

# Is the server responding to ping?
ping -c 4 your-server-ip

# Trace the network path
traceroute your-server-ip
mtr your-server-ip

# Check if specific ports are open
nc -zv your-server-ip 22
nc -zv your-server-ip 80

Common Causes

• Firewall lockout — accidentally blocked your own IP or SSH port
• Disk full — services crash when they cannot write logs
• OOM kill — SSH daemon killed due to memory exhaustion
• Failed update — kernel update requiring reboot, or broken network config
• DDoS attack — bandwidth saturated

Recovery via VNC Console

If SSH is unreachable but the server is running, use the VNC console from your hosting control panel:

1. Log into the Kazepute portal
2. Navigate to your Breeze
3. Click VNC Console
4. Log in and diagnose the issue

Prevention

• Always test firewall rules before disconnecting
• Set up monitoring and alerts
• Keep a backup SSH key and access method
