If you’ve installed Apache on Windows and are used to (re)starting the Apache service from a GUI interface, you’ll have a hard time debugging errors in your httpd configuration files, if there are any, since the GUI response will simply say
“The requested operation has failed!”
To figure out what the problem is, start Apache from the command line by changing to the directory containing httpd.exe and running httpd.exe, as shown below.
The problem here was there was a syntax error on line 87 of http-ssl.conf. The “ServerName” field should have been “ServerAlias”.
