local WampServer https: ERR_CONNECTION_REFUSED - ssl

Question

Edit: It looks like this issue is the root cause. The site in question is a http site, but it redirects to https automatically, so I decided to install an SSL cert to see the outcome. /end edit.
I followed the answer here to create a local SSL cert for my WampServer 3.1.0 64-bit.
I have made a local copy of our site, migrated the database to a new local URL (www.superiorit.dev), create an entry in httpd-vhosts.conf, and added a <VirtualHost www.superiorit.dev:443> entry in C:\wamp64\bin\apache\apache2.4.27\conf\extra\httpd-ssl.conf which contains the correct path to the .cert and .key files.
When I try to load https://www.superiorit.dev in the browser, I receive the error:
This site can’t be reached
www.superiorit.dev refused to connect.
Try:
Checking the connection
Checking the proxy and the firewall
ERR_CONNECTION_REFUSED
This is the entry in http-vhosts.conf:
<VirtualHost www.superiorit.dev:8080>
ServerName www.superiorit.dev
ServerAlias www.superiorit.dev
DocumentRoot "C:/wamp64/www/superiorit"

This is the entry in http-ssl.conf:

Help appreciated.
