Error: url must be a relative URL:

Hi all, I’m getting a scary error on my droplet when trying to get a Meteor app to run. At first it was just the first part, ‘http://httpheader.net’ but then overnight this weird Chinese hotel site showed up in the error log…

Does anyone know what’s happening here?
