Disconnect after new update

After the new update, I continually disconnected from the server. I reinstalled the game but it didn't work. This kind of experience has made my mentality like the stool. I was disconnected from the server in qualifying last night. This not only caused me to fail in the promotion, but also affected my mood. My LP point has only zero left. My ID is "Kallnumber2", and you can see how a bad luck has won a losing streak. . . . There are two teams I like in the S9 competition, and I hope that this will not happen in their games. . .
