<![CDATA[AdGuard Alias Cert not renewed]]>
  • I'm running Adguard Home to support DoT/DoH for Clients
  • limiting DNS to allowed clients is setup via Cloud Firewall, not within Adguard, ports 53 + 853 there are open for selected source IPs
  • adding a new alias for a dedicated client ('client1.gate') works and a valid cert is deployed in /etc/certs within AdGuard docker container
  • after some configuration changes and tests, I've been (again) adding the alias *.gate.mydomain.tld, which has been existing before and been removed again
    => creating the alias in Cloudron UI does not throw any error
    => however, an expired cert is used: when now accessing the AdGuard UI, an error message is visible on top saying
    58438ab0-45d6-4fd4-8476-3dfb38f4b4b4-image.jpeg
    =>I then renewed all certs via Cloudron Domain Mgmt, and regarding *.gate.mydomain.tld, the corresponding renewal log shows
    • 2026-04-30T12:04:23.234Z reverseproxy: ensureCertificate: error: no http challenges

    Am I facing the issue @girish described here?
    Any idea how to fix this?

    Thx in advance!

    now switched to Hetzner Cloud DNS, and the renewal worked. Thanks!

    Having used the manual wildcard config forever, I however still don't understand, how the first set of certs had been issued, that expired back in February.

    DNS is not automated for this Cloudron, all entries are set manually at the registrar's web UI
    Does that help?

    That is the issue. With a manual DNS provider, you can not get a DNS challenge.
    Only with a DNS challenge you can get wildcard certificates.
    This is causing your issues. You should switch to a supported DNS provider.

    Please include the output of cloudron-support --troubleshoot.
    What DNS provider are you using?
