Lost connection to EC2 instance


Can anyone tell me how to fix this?
Instance i-0c2471f7af8dd9d44 is running (and serving web pages via http on port 8080) but has stopped connecting via ssh - either through the browser console or via putty (console just says there was a problem, and putty times out before checking any credentials or anything)

I had fooloshly applied a Security Group which only allowed SSH from my own IP address --- and then my ISP changed it. Changing the security group solved the problem.
