Why is WSGIScriptAlias not having an effect? - apache

Question

I'm running into an issue with setting a WSGIScriptAlias in Apache, where attempting to use the alias is giving a 404 error due to trying to reach the "literal" URL. Here's the test set-up in my Apache2 sites-available/000-default.conf (mimicking the mod_wsgi Quick Start Guide):
DocumentRoot /var/www/html
WSGIScriptAlias /wsgi_test /var/www/html/test.wsgi
<Directory /var/www/html>
Order allow,deny
Allow from all
</Directory>
After restarting Apache2 and going to mydomain.com/wsgi_test, a 404 page is displayed. The first line of Apache's error.log file below shows the server attempting to access the URL path wsgi_test in DocumentRoot, not the aliased file path:
AH00128: File does not exist: /var/www/html/wsgi_test
AH01964: Connection to child 1 established (server nathanclonts.com:443)
(70007)The timeout specified has expired: [client 67.161.148.188:33883] AH01991: SSL input filter read failed.
The file /var/www/html/test.wsgi has the same code as the above-mentioned Quick Start Guide:
def application(environ, start_response):
status = '200 OK'
output = b'Hello World!'
response_headers = [('Content-type', 'text/plain'),
('Content-Length', str(len(output)))]
start_response(status, response_headers)
return [output]
With permissions set to:
-rwxrw-r-- 1 username www-data 278 Apr 16 11:31 test.wsgi
Does anyone have suggestions on where to look for other configuration that may be affecting this, or any other debugging tips?
What's odd is that I have set up another (Django) application with mod_wsgi that is currently working in the same VirtualHost, but obviously I'm missing something in this test.

This was resolved by updating the <VirtualHost *:443> configuration file to include the WSGIScriptAlias line (as the server uses SSL), instead of having WSGIScriptAlias under the <VirtualHost *> configuration.
I wasn't aware that all Aliases needed to be included in the 443 port to function, but eventually worked it out after playing with a vanilla Alias and locating which files they were defined in with:
grep -R "Alias" /etc/apache2/*
