I had the same problem as you before. I always fail to log in. I can reconnect the network cable, but not next time. Later, I found that the right-click property of your broadband connection is like this. Then I clicked Advanced and then Settings. Speaking of the abnormal firewall settings page, I clicked Add Program, and then I decided to add the same city game. That's how I got it. Hehe, I wonder if it will help you.
