SOLVED: After many days of tinkering i finally found the issue which was causing none of the challenge types. I am using DigitalOcean as my DNS (as shown in the values.yaml), but had a Droplet there with a name similar to my domain. Apparently DigitalOcean automatically creates PTR records for droplet names which match a domain controlled by their DNS. When I had renamed this droplet to something different a clean installation of Traefik worked.
