You are using a windows service to start Apache, so is there anything in the windows event logs giving more information about this error?

The error said closed door.
And this has deceived me.
The problem was in the vhost file.
It had to be a particular character.
I deleted the last vhost and redid the wording and configuration.
now it works properly.
Thank you for your quick answer.
