This problem suddenly occurred when I was working on a project recently , Command line connection mysql That's all right. ,sqlyog No problem connecting , But the code compiler can't connect normally , I tried a lot of things, but they didn't work , Finally, I found that it was the problem of Zen

This process is running , Maybe the user name and password conflict , It will cause abnormal connection , It's no problem to close it .
