Hi, I'm using EC2 Ubuntu Server 14.04 LTS (HVM). It worked fine for a few days then somehow I couldn't connect any more. Appreciate your help....Some log from server:

You could just get rid of that one instance and create a new one. It will probably start working again then ;)

In general I would recommend switching to this solution. It's more modern: https://github.com/hwdsl2/setup-ipsec-vpn
