TLS certificate fails to issue for custom domain done-in-21.dk

Question

Custom domain [done-in-21.dk](http://done-in-21.dk) has been failing to provision TLS certificate for 24+ hours.

**Details:**

* Service: landing
* \- Domain: [done-in-21.dk](http://done-in-21.dk)
* \- DNS: Correctly configured ALIAS to [m3gy9hbu.up.railway.app](http://m3gy9hbu.up.railway.app)
* \- DNS verified via nslookup - resolves to 66.33.22.186
* \- Other domains on same service work fine: donein21.dk, [done-in-21.com](http://done-in-21.com)

**Error:** "Failed to issue TLS certificate"

**Steps tried:**

* Clicked "Try Again" multiple times
* \- DNS was initially wrong (pointing to old endpoint vjebscll.up.railway.app)
* \- Fixed DNS to correct endpoint ([m3gy9hbu.up.railway.app](http://m3gy9hbu.up.railway.app))
* \- DNS has fully propagated (verified via Google DNS 8.8.8.8 and Cloudflare 1.1.1.1)
* \- Certificate provisioning still fails after DNS fix

Could you please check the certificate provisioning queue or reset the domain state?
