Installed self-signed SSL certificates, Apache won't start - apache

Question

I'm trying to build a website which requires the Stripe payment gateway, and therefore requires SSL. I'm using XAMPP on Windows 10. After generating SSL certificate and key pair and installing in Apache, Apache no longer starts.
I'm attaching a few error messages and configs. Please help.
This is message in Apache error log. It no longer reproduces these error messages. So something must've changed. I think I tried generating the certificate and key via a different method. But Apache still won't start.

This is the error I get when trying to start Apache from command line.
Apache 2 is starting ...

This is what is in httpd-vhosts.conf. I'm trying to setup SSL for loc1.dev.
<VirtualHost *:80>
DocumentRoot "C:/xampp/htdocs"
ServerName localhost
</VirtualHost>
<VirtualHost *:80>
DocumentRoot "C:/xampp/htdocs/loc.com/public_html"

ServerAlias www.loc.dev
<Directory "C:/xampp/htdocs/loc.com/public_html">

</Directory>
</VirtualHost>
<VirtualHost *:80>

This is what I have in httpd-ssl.conf
<VirtualHost _default_:443>
# General setup for the virtual host

ServerName www.loc1.dev
ServerAdmin jonathan.najman#gmail.com
ErrorLog "C:/xampp/apache/logs/error.log"
TransferLog "C:/xampp/apache/logs/access.log"
SSLEngine on
SSLCertificateFile "conf/ssl.crt/server.crt"
SSLCertificateKeyFile "conf/ssl.key/server.key"
</VirtualHost>
This is what is in my hosts file (C:\Windows\System32\drivers\etc\hosts).
127.0.0.1 localhost
127.0.0.1 loc.dev
127.0.0.1 loc1.dev
127.0.0.1 foodharbor.dev
Am I missing anything?

Answer 1

I commented out Listen 443 in httpd-ssl.conf (C:\xampp\apache\conf\extra) and now Apache starts and the site is available on https and http. There must already be a directive elsewhere directing Apache to listen on 443 ...
#
# When we also provide SSL we have to listen to the
# standard HTTP port (see above) and to the HTTPS port
#
#Listen 443
