Well, as we may see, something is blocking traffic between you and mb2 master server not far away from master server.
That may happen for various reasons, the one is that MBII developers OR their hosting company has banned you OR whole your ISP.
You should post your IP here. Here's some sites that print your IP address in case you don't know it:
Ваш IP-адрес. Узнать IP адрес, определить IP-адрес, определить свой IP
IP-Secrets - What is my IP?
What Is My IP Address? IP Address Tools and More
Back in the day, I used to cast LoU to this kind of threads, but now I think
@Defiant may be a more appropriate choice.
So MBII devs, would be nice if you checked what happened to OP's access to your master server.
Hiazro, there is also an another way to solve your issue.
In case MBII devs won't be able to help you, or you just do not want to wait, it's possible to edit HOSTS file in order to switch to other MBII master server, provided by jkhub.org. I hope you aren't banned there.
