ok im getting this a the response for the authentification request: https://hastebin.com/hahataquqe.json looks like youll have to report it to them ... they changed the server to which you authenticate to but forgot to setup the service responsible for it. (Documentation on how the answer should look like can be found here: http://wiki.vg/Authentication)

thank you, to tell
