I had an issue on one of my EC2 servers starting last night. A few of the apps running on it were not accessible over the net.#
I figured one of my code updates had broken something, but I couldn't find a common thread between the apps. They were xmlviewer, river5 and jsonchat. #
xmlviewer is the simplest so I started with that. #
Then I checked if the port was open in the EC2 firewall. It wasn't. There was the problem. I opened the three ports for the three apps and voila, they are working again.#
Which leaves me with a mystery. I can't imagine I woke up in the middle of the night, in a dream, opened the EC2 console and deleted the entries for the three ports. But they weren't there.#
