I have tried several times to Clone a new server from latest snapshot however the new server seems completely impervious to my attemps to either SSH or Webshell into it as required below. Hence I have no way of accessing the Snapshot. The console log all looks fine, nothing unexpected.

Anyone got any bright ideas of how to get it working? 

Snapshot launch: manual action required

This server contains configurations specific to the original snapshot server, and requires reconfiguration. Please log into this server (SSH or Webshell) as root, and execute the following:

/usr/lib/inithooks/firstboot.d/25ec2-userdata
