Kubernetes order no state

I recently transferred my domain name legioncapital.ch to a different account on my registrar. But I messed up my kubernetes config in doing so and the HTTPS certificate now seems broken.

It is broken at the order level:

kubectl get order
NAME                          STATE   AGE
legion-tls-hfk6c-2181229722           5m4s

As you can see, the state is not setting itself

Also:

kubectl get challenge                                                                                          
Error from server: conversion webhook for acme.cert-manager.io/v1alpha2, Kind=Challenge failed: Post "https://cert-manager-webhook.cert-manager.svc:443/convert?timeout=30s": x509: certificate signed by unknown authority (possibly because of "x509: ECDSA verification failure" while trying to verify candidate authority certificate "cert-manager-webhook-ca")

My domain is: legioncapital.ch

My web server is (include version): Nginx

The operating system my web server runs on is (include version): Kubernetes

My hosting provider, if applicable, is: Digitalocean

I can login to a root shell on my machine (yes or no, or I don't know): Yes

The version of my client is (e.g. output of certbot --version or certbot-auto --version if you're using Certbot): cert-manager.io/v1
