Let's Encrypt certificate renewal failed

I used to have a Let’s Encrypt certificate in use. It expired a few days back so I clicked on the “renew” button to renew it. The popup notification on top saying it’s done successfully as shown in attached screenshot. However, the expiration date was never changed, that is, nothing happenning and it’s actually not renewed. I have tried this quite a few times in different time. Can anyone help?

Besides, when I clicked on the “Revoke” button, it would fail and replicate the same expired certificate and show up in the list.

Hello Duke,

Please check your Axigen logs for any hints on why the renewal process failed (look after lines containing LetsE: string).

I could only imagine that you have disabled access on port 80 and this is why LE service could not check the token before generating the new certificate.

Bottom line: when using LE certificates you need to keep port 80 open. The recommended way is to have both HTTP and HTTPS listeners enabled and configure the automatic redirection from HTTP to HTTPS.

And, by the way, if all is left as described above, the certificate will be renewed automatically as there is a periodic job that have this task.

HTH,
Ioan

You are right! Port 80 was blocked in router. Resolved now. thx.

Hi. I have the same issue, but port 80 isn’t blocked. It was working fine, but then on Aug 17 it didn’t renew automatically. I have replaced the cacert.pem file like described here : LetsEncrypt certificate renewal failing and it does not work.

Here is the kind of messages I see in the logs, I have replace my actual domain name with www.example.com :
