Renewal Certificat Nitrokey Nextbox

Hi,

My Nextbox is not able to renew the TLS certificates. I had a look at the logs, and there are repeated errors, both in letsencrypt.log and nextbox.log, e.g.

2022-01-27 00:24:48,960:INFO:certbot.hooks:Output from nextbox-desec-hook.sh:

How get it to be renewed?

Thanks for any hints!

Hey @ffo,

this is weird, http error 401 means unauthorized, which I would assume means you cannot be authorized by desec to create your dns entry there. So I would first recommend to renew these:

  • login into your desec account (make sure this is the account which has your subdomain registered) go to “tokens” and create a new one, note down the auth token you receive
  • disable tls
  • in guided dns also disable it
  • then you should see your last domain + e-mail, verify that this is the e-mail which has the domain registered at desec
  • then go to step two directly without registering (button on the right side: “Next (without register)”)
  • insert your earlier received desec auth token
  • enable dns
  • enable tls

hope this helps
best

Hi @daringer ,

Thanks for the help. I went through all steps, and that seemed to work fine, until I went to the page where the certificate information is shown. It turns out the certificate was not renewed, and is still expiring on 3 Feb. So, unfortunately, the problem is not solved yet. Was the certificate not removed?

Hey @ffo,

yes this is expected, as enabling TLS with an (locally) existing certificate will re-use this certificate, now please wait 24h so certbot can try to renew it, hopefully the expiry date should then be back at 90days again, if not, please recheck the logs.

The certificate renewal has worked now. Thanks!
