Hi @shtirlic
you have ipv4- and ipv6 - addresses ( https://check-your-website.server-daten.de/?q=mystery-home-shop.com ):
| Host | T | IP-Address | is auth. | ∑ Queries | ∑ Timeout |
|---|---|---|---|---|---|
| mystery-home-shop.com | A | 88.99.87.195 | yes | 1 | 0 |
| AAAA | 2a01:4f8:c17:6a9c::2 | yes | |||
| www.mystery-home-shop.com | A | 88.99.87.195 | yes | 1 | 0 |
| AAAA | 2a01:4f8:c17:6a9c::2 | yes |
But your http + ipv6 doesn't work:

Looks like your port 80 / ipv6 isn't configured or blocked by a firewall.
That's critical, because Letsencrypt prefers ipv6.
So
- check your firewall settings and check, if ipv6 is configured (or)
- remove the ipv6 AAAA entry, create a certificate, then fix your ipv6
