For some reason, my AWS instance has stopped accepting connections today. The Cloud appliance library shows the instance active, I click on the connect and it comes back with an error indicating that the host is not available. I have also tried to connect from Eclipse on my desktop, it now asks for a user and password and does not accept the 'SYSTEM' user that was working fine previously. Any ideas on how I find out what has happened or what to do - I have suspended and the re-activated the instance with the same negative result.

Many Thanks
