    Hello @Damian,

    As I understand, you also have the error "Tcp port is already in use" in the event viewer.

    In case you have installed additional MySQL server, make sure you have used all recommendations from this article:

    If you are using only MySQL provided by Plesk, some other process could have occupied the required port. To check who is listening to it use the command in CMD:

    netstat -a -b
    After finding the process, stop it and start MySQL server again.
