Node Workspace Preview not working


Everything was working fine when I logged off yesterday, but this morning when I logged in my preview will not work for my webdevbootcamp workspace. I started up the DB and the application and then went to Preview and Preview Running Application and get a page saying no application is running. I am not getting any errors displayed in the terminal when starting the DB or application. Any ideas?

edit: issue resolved. This started during some problems this morning. Had to reboot again and shut out of c9 and then come back in.
