I was playing earlier this morning (4 a.m central), and left the game open to take care of a few real life things. I came back at 6, and the game had lost connection. I tried reconnecting, and it says "This game is awaiting a response from battle.net". I've tried a number of things, including running as administrator, checking my forwarded ports/firewall, running the repair feature, restarting my computer, and resetting my internet connection. I've been playing for months now, and this is the only time I've ever had this issue. Nothing on my computer was changed, so I don't understand what the problem is. The Battle.net server is up, and obviously I can connect to the internet. As far as I know, I'm running the latest version (1.3.4). I've checked the forums and did some google searches and have found some suggestions, but nothing I haven't tried before hand. Anyone have any bright ideas? Thanks in advance!
I have the same problem as you. I got it fixed after restarting StarCraft2. It seems the problem lies with B.net. Hopefully you won't have any problems after a few hours.
