Prerequisites; Cluster creation; Cluster destruction . This one was hard to catch because I guess most of the time browsers such as Firefox, Safari and Chrome latest version are able to figure out what certificate to pick from the ones Traefik serves via TLS and ignore the unmatching non SNI default cert, however, the same browsers some time stutter and pick the wrong one which is why some users sometimes see a page flagged as non-secure.
