I've never had any connection problems in the past. Now, after the new release I can't connect at all (W10, Firefox 54.0.1) and only get the "Server connection was closed or could not be established." message. I even restarted my computer. No luck. Please help.
EDIT: I can now connect again. I'll still be a little concerned until I see the problem doesn't recur, but for now it's all good.
