Fix rsync Failed to Connect to cPanel Error

Introduction:

When updating cPanel with /scripts/updatenow, you may encounter the “rsync failed to connect to cPanel” error:

rsync: failed to connect to rsync.cpanel.net: No route to host

This happens when firewall rules block cPanel update ports. Here’s how to fix it step by step.

Steps:

1. Run the update command to confirm the error:
   /scripts/updatenow
2. Allow outgoing connections through ports 2080–2099 in your firewall:
   iptables -I INPUT -p tcp –dport 2080:2099 -j ACCEPT
   iptables -I OUTPUT -p tcp –dport 2080:2099 -j ACCEPT
   service iptables save
   service iptables restart
3. Run the following commands as root to refresh cPanel:
   /usr/local/cpanel/cpkeyclt
   rm -f /usr/local/cpanel/cpanel
   /scripts/upcp
4. Verify the update again with:
   /scripts/updatenow

Pro Tip:

Always keep firewall rules updated and ensure cPanel ports (2080–2099) remain open to avoid future sync failures. Regular updates help maintain server security and performance.
