Hi Michiel
Here is the bnsupport_tool output for the current situation "bc9915dd-96b4-ed59-853b-ab5d0fa174b5". This has HTTPS requests turning into HTTP. The previous situation had bncert-tool adding HTTP to HTTPS so the two would explain the redirects problem.
The only other thing I ran was "sudo /opt/bitnami/apps/prestashop/bnconfig --machine_hostname shop.glowsystems.co.uk http://shop.glowsystems.co.uk/"
The DNS table has an A record for shop.glowsystems.co.uk http://shop.glowsystems.co.uk/, and a CNAME record www.shop.glowsystems.co.uk http://www.shop.glowsystems.co.uk/.
