Authhash problem

[DJInsaNITY74]

I got my server from free-shoutcast.com and use virtualdj to broadcast, and until yesterday, everything was alright. Now, I keep getting a message, saying I have to update my authhash. Also, that same site instead of the usual maintance pages now points to nginx. My stream still works and I can connect to it, but I keep getting this message. Does anybody know what's happening with this?
