Can Someone help me?
I typed in the server.cfg nothing false

Because of that, the essentialmode cant run

Are you using XAMPP correctly? Make sure the service is running, everything is hosted properly and that you put the correct credentials in (the IP, port, whatever)

I am using Linux MySQL

Check config.d from MySql if its allowing connections
