This website is currently hosted through gitlab-pages. The current domain davidhendriks.com is managed on Transip, and I experienced some issues with linking the domain to the gitlab-pages. It seems that the explanation provided by gitlab-pages does not work with the Transip control panel. I found a write-up by someone with the same issue: https://0to1.nl/post/2020-09-11-gitlab-transip/, which helped my with solving the issue, but I still had to change several of the solutions he provided.
