How did the original poster solve the problem? I also encountered the same problem. It worked before, but this problem occurred after upgrading the Xiaopi panel to 8.1.1.3
replyThe main reason is that the mysql that comes with phpstudy occupies 3306. I think that if you study, you can also use the mysql that comes with it.
replyI know that the service is not supported, but I followed this course and used phpstudy. I installed mysql myself. I installed 5.5. I don’t know what is the reason why sql error is reported for 3.22, 3.23 & 4.0 servers

Then choose a higher version of php

The error reported is that the service is not supported.
