Hello Graham,
Sorry I missed the argument in Directory. I have now changed the configuration
file as below.
(env) hd2900@hd2900:~/Documents/Python/hd2900TakeawayPrint$ cat
/etc/apache2/sites-enabled/000-default.conf
<VirtualHost *:80>
# The ServerName directive sets the request scheme, hostname and port
that
# the server uses to identify itself. This is used when creating
# redirection URLs. In the context of virtual hosts, the ServerName
# specifies what hostname must appear in the request's Host: header to
# match this virtual host. For the default virtual host (this file) this
# value is not decisive as it is used as a last resort host regardless.
# However, you must set it for any further virtual host explicitly.
#ServerName www.example.com
ServerAdmin webmaster@localhost
DocumentRoot /var/www/html
WSGIDaemonProcess flaskapp threads=5
WSGIScriptAlias / /var/www/html/flaskapp/flaskapp.wsgi
WSGIApplicationGroup %{GLOBAL}
<Directory /var/www/html/flaskapp>
WSGIProcessGroup flaskapp
Require all granted
</Directory>
# Available loglevels: trace8, ..., trace1, debug, info, notice, warn,
# error, crit, alert, emerg.
# It is also possible to configure the loglevel for particular
# modules, e.g.
#LogLevel info ssl:warn
ErrorLog ${APACHE_LOG_DIR}/error.log
CustomLog ${APACHE_LOG_DIR}/access.log combined
# For most configuration files from conf-available/, which are
# enabled or disabled at a global level, it is possible to
# include a line for only one particular virtual host. For example the
# following line enables the CGI configuration for this host only
# after it has been globally disabled with "a2disconf".
#Include conf-available/serve-cgi-bin.conf
#Header set Access-Control-Allow-Origin "*"
</VirtualHost>
Furthermore I have ensured that the dynamic link is created as seen below in
the path /var/www/html
(env) hd2900@hd2900:/var/www/html$ ll
total 20
drwxr-xr-x 2 root root 4096 Oct 10 18:38 ./
drwxr-xr-x 3 root root 4096 Sep 26 21:54 ../
lrwxrwxrwx 1 root root 19 Oct 10 18:38 flaskapp -> hd2900TakeawayPrint
-rw-r--r-- 1 root root 10918 Sep 26 21:54 index.html
In the hd2900TakeawayPrint folder the flasapp.wsgi is located
(env) hd2900@hd2900:~/Documents/Python/hd2900TakeawayPrint$ ll -la
total 32
drwxrwxr-x 4 hd2900 www-data 4096 Oct 10 18:23 ./

drwxrwxr-x 4 hd2900 hd2900 4096 Oct 10 18:08 env/
-rwxrwxr-x 1 hd2900 www-data 249 Oct 10 18:23 flaskapp.py*
-rwxrwxr-x 1 hd2900 www-data 96 Oct 10 18:23 flaskapp.wsgi*

-rwxrwxr-x 1 hd2900 hd2900 69 Oct 10 18:04 README.md*
Still when I from a browser type https://my-global-IP:81
<https://myglobalip:81/> I get the permission error.
Best regards,
Jian
