Sadly there are no logs, even with debug log level.

[Fri Mar 13 10:30:21.540225 2020] [ssl:info] [pid 20705:tid 139956984929216] AH01887: Init: Initializing (virtual) servers for SSL

Then a timeout is reached and the apache start fails.

I have switched the Apache module "mpm_event" to "mpm_prefork" no it works.
