SSl expired on virtualmin

[phenomlab]

@justoverclock Hi, and happy new year !

If you go to Virtualmin->Server Configuration->SSL Certificate->Let’s Encrypt, what values do you see in the below ?

[justoverclock]

@phenomlab happy new year to you also!

[phenomlab]

@justoverclock Ok, that’s because you have no wildcard DNS record, and it’s attempting to renew for domains you don’t have listed in DNS.

Select the second option, and enter justoverclock.it and proceed that way.

Note, that there is a rate-limit set to 10 per hour, so if you exceed this, you’ll need to wait for a while then try again. In this case, you’d see this message

@phenomlab oh, i need to request new certificate or renew?

[phenomlab]

@justoverclock Try to renew it. If that doesn’t work, then request a new one

[justoverclock]

@phenomlab nothing happen

[phenomlab]

@justoverclock Yep, that’s the rate-limit message. Try again in an hour.

[justoverclock]

@phenomlab after one hour or more:

[phenomlab]

@justoverclock Seems your _acme-challenge DNS record is missing ?

[justoverclock]

@phenomlab didn’t touch anything from your last visit

[phenomlab]

@justoverclock Very odd. Let me have a look at another way

[phenomlab]

@justoverclock I have installed the --nginx version of certbot on your server as per
https://sudonix.com/post/689

It’s showing that the renewal will work, but the rate-limit is currently still enforced, so we still need to wait.

IMPORTANT NOTES:
 - Your account credentials have been saved in your Certbot
   configuration directory at /etc/letsencrypt. You should make a
   secure backup of this folder now. This configuration directory will
   also contain certificates and private keys obtained by Certbot so
   making regular backups of this folder is ideal.
root@justoverclock:/home/justoverclock#

[phenomlab]

@justoverclock should be resolved now

As a side note, this renewal won’t show in Virtualmin unless it is requested from there. This is done from the command line, so

1. SSH into the server
2. Change to root
3. Execute certbot --nginx and follow the prompts

[justoverclock]

@phenomlab so this is the command that i need to use everytime my certificate expire? thank you, precious as always

[phenomlab]

@justoverclock Not necessarily. You only need to use this if it fails from the Virtualmin window
