从昨天开始，UT SQB 的正常模式一直无法连接，只需点击一下就会返回主菜单，但选择模式正常。UT的另外一个在线模式也很正常，所以想问怎么解决

Since yesterday, the normal mode of UT SQB has been unable to connect, and just a click will return to the main menu, but the select mode is normal. The other online mode of UT is also normal, so I would like to ask how to solve it
