Let’s Encrypt SSL failed to renew certificate

nelsonmedina · August 13, 2022, 12:26pm

Please fill out the fields below so we can help you better. Note: you must provide your domain name to get help. Domain names for issued certificates are all made public in Certificate Transparency logs (e.g. crt.sh | example.com), so withholding your domain name here does not increase secrecy, but only makes it harder for us to provide help.

My domain is: nelsontalk.info

I ran this command: certbot renew --force-renewal

It produced this output:
Challenge failed for domain mymail.nelsontalk.info
http-01 challenge for mymail.nelsontalk.info
Cleaning up challenges
Attempting to renew cert (nelsontalk.info) from /etc/letsencrypt/renewal/nelsontalk.info.conf produced an unexpected error: Some challenges have failed.. Skipping.
All renewal attempts failed. The following certs could not be renewed:
/etc/letsencrypt/live/nelsontalk.info/fullchain.pem (failure)

All renewal attempts failed. The following certs could not be renewed:

Welcome to the community @nelsonmedina

Can you show us the contents of this file:

Osiris · August 13, 2022, 3:04pm

Please do NOT use this option if you're not familiar with it's function. It does NOT magically resolve validation errors from the side of the ACME server (obviously). Using the --force-renewal function improperly can lead to hitting rate limits.

nelsonmedina · August 13, 2022, 4:33pm

Sure check below

MikeMcQ · August 13, 2022, 5:34pm

Thanks. Locate the apache VirtualHost for mymail.nelsontalk.info. Then, is the DocumentRoot still /home/nelsontalk/public_html ?

If you are not sure how to find this, please show result of this command:

apachectl -t -D DUMP_VHOSTS

nelsonmedina · August 14, 2022, 11:22am

Sure, here you have it.

MikeMcQ · August 14, 2022, 1:20pm

Thanks. Now can you show the contents of this file

/etc/apache2/sites-enabled/mymail.nelsontalk.info

Is it possible for you to upload this file or to copy/paste the info? Images of text are harder to work with. If you copy/paste please put 3 backticks before and after the text like this
```

Could you edit your post to use 3 backticks. It looks like you used 3 single quotes instead.

Sometimes apache config items are lost if you don't use backticks

Osiris · August 14, 2022, 2:02pm

The 'backtick' is usually located left from the "1" at the left of the keyboard

MikeMcQ · August 14, 2022, 2:17pm

The backticks would still be helpful. But, I see a problem. Your Apache DocumentRoot for that domain name is /home/mymail/public_html

But, the webroot path in certbot renewal is /home/nelsontalk/public_html.

These two paths must match. So, to give best instructions on how to fix please show output of the certificates command (with backticks as shown)

```
output of command: certbot certificates
```

nelsonmedina · August 14, 2022, 3:37pm

Here is:

Found the following certs:
  Certificate Name: nelsontalk.info
    Domains: nelsontalk.info mymail.nelsontalk.info
    Expiry Date: 2022-08-10 00:04:06+00:00 (INVALID: EXPIRED)
    Certificate Path: /etc/letsencrypt/live/nelsontalk.info/fullchain.pem
    Private Key Path: /etc/letsencrypt/live/nelsontalk.info/privkey.pem

MikeMcQ · August 14, 2022, 3:43pm

Thanks. This should renew successfully and update the renewal conf for next time

certbot renew --cert-name nelsontalk.info -w /home/mymail/public_html

nelsonmedina · August 14, 2022, 4:22pm

I typed the command, and it did the update and refresh successfully; however, it is not updated yet.

MikeMcQ · August 14, 2022, 4:28pm

You will need to restart Apache to get the new certificate

nelsonmedina · August 14, 2022, 4:49pm

I did it, but nothing happens, still the same.

MikeMcQ · August 14, 2022, 5:02pm

That's very strange that restart was not enough. Please show this again

```
output of command: certbot certificates
```

MikeMcQ · August 14, 2022, 5:03pm

Nevermind. I see your server is now sending the current cert. It was not when I checked just before but I am glad you got it sorted.

nelsonmedina · August 14, 2022, 5:25pm

Is done

Thank you so much for your help
