Hi guys!

Since the new update have been released i've been unable
to login to Minecraft. The problem is that, everytime I try to login a
error is popping up: Can't connect to Minecraft.net Any suggestions?

And
I have another problem with server. Everytime I want to log on to a
server via the in browser game, I get this message: Internal client
error: Java.net.ConnectionException: connection refused: connect.

Thanks for reading! Any help with one of this two problems would be very apprectiated!
