Hey @steffenmllr, we took a closer look and it seems like there’s a stray IPv6 record that’s conflicting with the A record pointing to our load balancer:
loooop.de has IPv6 address 2a01:488:42:1000:50ed:8223:e6:fd0
Can you delete that record at your domain host and see if that makes it possible for you to get your SSL cert in our UI?
