Issue with renewing Certificate

Hi Group,

3 Month before I have installed a Lets-Encrypt Certificate for our website.
Now i got a reminder, that the Certificate is due to expire, so now i am trying to extend it.

We are using apache to serve our homepage.

After some excessive trials i hit the Limit of 5 Trials, so one week later i am trying again

This is what i did this time:
service httpd stop
certbot --verbose --agree-tos --email renew

but it fails after some seconds.

Pasting the relevant sections from /var/log/letsencrypr/letsencrypt.log are in the bottom of the topic.

What can be the issue ? Do i need to specify a password or could it be to wrong 80-> 443 redirection ?

Thank you for your Attention

Best regards …

How is it possible the certbot error log has a HTML answer in the response from the request when you’ve stopped your httpd? That shouldn’t be possible.

Also, how did you request the certificate in the first place? With what command?

Hi Osiris,

Thank you for your attention.

When it was not working, i read on the internet, that a user succeeded when turning off his apache service, so did i.
Now I believe that the certbot has just started it again, this is why we see HTML output.

I installed certbot according to the documentation given:

sudo certbot --apache

However i remember that i was editing the apache config files to properly include the lets-encrypt certificates.

Please find attached my certbot log and other files of interest

(Attachment letsencrypt.log is missing)

(Attachment virtualhost.conf is missing)

(Attachment ssl.conf is missing)


please find attached the files with txt extension

Thank you
