The bot didn't fully connect. You may be IpBanned. Wait awhile and reconnect again.
Remember you can't have more than 8 connections per IP to battle.net. If you do so you would get disced.
As you can see it still says 0p/s. Once that number starts moving up you know the bot is working.
If you still can't connect, let me know if you can connect to the same connection via D2 game and if you have more than 8 connections to that same server, i.e bots, etc.
