Dear Graham, the wsgi.py file exists.
[root@server app]# ls -ltr /opt/app/app_prod/app/wsgi.py
-rw-r--r-- 1 app_user app_user 411 Mar 18 06:53 /opt/app/app_prod/app/wsgi.
py
There is no other entity using the port 8999
[root@server app]# netstat -an | grep 8999
tcp6 0 0 :::8999 :::* LISTEN
[root@server app]# service httpd stop
Redirecting to /bin/systemctl stop httpd.service
[root@server app]# netstat -an | grep 8999
[root@server app]#
If i put in the QA wsgi app it works. Below is the config.
WSGISocketPrefix /run/httpd/wsgi/
<VirtualHost *:8999>
WSGIDaemonProcess app_qa processes=1 display-name=%{GROUP} python-path=/opt/
app/app_qa/app
#WSGIProcessGroup app_qa
WSGIScriptAlias /app_qa /opt/app/app_qa/app/wsgi.py process-group=app_qa
application-group=%{GLOBAL}

</Files>
</Directory>

</VirtualHost>
If i put in the PROD wsgi app it does not works Below is the config.
WSGISocketPrefix /run/httpd/wsgi/
<VirtualHost *:8999>
WSGIDaemonProcess app_prod processes=1 display-name=%{GROUP} python-path=
/opt/app/app_prod/app
