This is an (unfortunately) known issue with the web server providing status information. At the beginning of the year I started forcing all HTTP:// requests to the Foundry web server to be redirected to secured HTTPS:// pages. I put an exception in the rewriting rules for the game status request URL, but apparently it is not working despite a couple of adjustments to the exception. You're seeing the beginning of the redirect message as the header of the launcher since the game knows neither about redirects, nor how to handle SSL traffic.
It's been on the ToDo list for some time, but always seems to get pushed below the "next" task.
It won't be broken on MOULa, unless Chogon makes the same silly upgrade.
