So I decided to switch servers from GitHub pages to another and so I just deleted the repository in GitHub pages and uploaded my more recent website files to the new server. I deleted and changed the DNS in my domain provider too. Now www.adamtutor.co.uk works with the new server, but adamtutor.co.uk doesn’t. I came here to check if the https:// that is still attached to my domain (https://adamtutor.co.uk) from GitHub via letsencrypt is stopping me from attaching it to the new server? If my repository in GitHub is deleted why is the https still attached to the domain?
