While trying to turn a server offline via the browser, I received an generic error message, which led to the browser options then being 'greyed out', unable to click any option. So I closed the browser, and the console to end it that way, but upon restarting the dedi server option, it fails to register or announce. Tied restarting the machine and reinstalling the app, without success: Error, which repeats: http://prntscr.com/7cu5vs EDIT: it has now come back, after around 15 minutes.
I am having the same problem right now. Was working earlier, must be related to the other server issues going on.
