Repo.nitrokey.com DNS issue?

Hi there, I am wondering about the following - what’s going on?

repo.nitrokey.com DNS resolution failing

System: Ubuntu 22.04.5 LTS (jammy)

Issue: The Nitrokey repository at repo.nitrokey.com is failing DNS resolution, causing apt update to fail when fetching from this source.

Error output:

Ign:14 https://repo.nitrokey.com/ubuntu jammy InRelease
Fehl:14 https://repo.nitrokey.com/ubuntu jammy InRelease
»repo.nitrokey.com« konnte nicht aufgelöst werden.
W: Fehlschlag beim Holen von https://repo.nitrokey.com/ubuntu/dists/jammy/InRelease »repo.nitrokey.com« konnte nicht aufgelöst werden.

DNS investigation:

  • Multiple DNS servers (1.1.1.1, 8.8.8.8, local resolver) all return “No answer” for repo.nitrokey.com
  • dig repo.nitrokey.com NS shows no nameserver records for the subdomain
  • Main domain nitrokey.com resolves fine and uses Cloudflare DNS (skip.ns.cloudflare.com)
  • Domain registration is valid until 2025-08-15

Question:

Is this a known infrastructure issue? Has the repository been moved to a different URL, or is this a temporary DNS configuration problem?

Any guidance on the correct repository URL for Ubuntu 22.04 would be appreciated.

Thank you!

something seems to have been fixed just today, great, it works now!

here (note I also upgraded that system to 24.04 - but I don’t think that was related … but not entirely sure - anyways:
