This been happening for a long time and now I've decided to make a thread about this. When I first played BvZ this didn't occur as much. It usually happens a couple of times and then it can finally connect to BvZ. Now I can't connect to BvZ at all and this been happening for months. This is what it says when I try to connect to BvZ: Could not connect to default or fallback server, please try again later: java.net.ConnectException
No need to worry, everyone got the same problem. They are changing something be patient and all will be fixed.
Blocks vs. Zombies has been down for what, 2 months now. I asked the admin and he replied saying that he doesn't know why and he will ask Noobcrew.
