Successful DNS verification but Let’s Encrypt provision keeps failing

[martin_s]

Hey there!

A couple of weeks ago I successfully connected a custom domain to my netlify site:
http://stroh.netlify.com/ → http://strohballensiedlung.de

The HTTPS section in Domain Management gives me the “DNS verification was successful” message:

But Let’s Encrypt keeps failing me: “We could not provision a Let’s Encrypt certificate for your custom domain.”

I checked my DNS records and everything seems fine. After 2+ weeks TLL shouldn’t be an issue either.

Can you guys give me any pointers to solve this problem?

Greetings
Martin

Your DNS records are unfortunately not fine.

$ host strohballensiedlung.de
strohballensiedlung.de has address 104.198.14.52
strohballensiedlung.de has IPv6 address 2607:7700::1c:0:1:68c6:e34

the IPv6 record does not point to our CDN, and thus our SSL provider does not believe that we host your website. Once you remove it, things will likely work better

Solved. Thank you!
