"java.net.connectexception connection refused" when connecting via ssh on Android

I was connected last night via JuiceSSH on Android viewing and rsync transfer from my old box. Then all the sudden I try to connect I get a connection refused. When I try to connect via AndFTP I get
java.net.connectexception connection refused
However connecting on my pc works fine. And using the IP address on android also works fine.
Any ideas?
