Renewing expired certificate fails

[siramthar]

Hello,
I have not been able to renew the certificate of this server:

My domain is: mail.stage-gate.la

I ran this command: sudo certbot --apache --agree-tos --redirect --hsts --email german.garcia@stage-gate.com --renew-by-default -d mail.stage-gate.la

It produced this output:

  entered correctly and the DNS A/AAAA record(s) for that domain
  contain(s) the right IP address.

My web server is (include version): apache

The operating system my web server runs on is (include version): ubuntu 16.04

The version of my client is Certbot 0.31.0

---

I added a test.html at the server to see if it was been able to get accessed through a browser and if apache was blocking it or not.:
http://mail.stage-gate.la/.well-known/acme-challenge/test.html
It opens fine.

What can I do? I’m lost.

Thanks in advance!

Hello,
I removed the redirect from apache at /etc/apache2/sites-available/mail.stage-gate.la.conf :

RewriteEngine on
RewriteCond %{SERVER_NAME} =mail.stage-gate.la
RewriteRule ^ https://%{SERVER_NAME}%{REQUEST_URI} [END,NE,R=permanent]

–
Also at /etc/apache2/sites-available/000-default.conf:
I commented the line

enableSSL on

---

Then I ran
sudo certbot run -a webroot -i apache -w /var/www/mail.stage-gate.la -d mail.stage-gate.la

Please choose whether or not to redirect HTTP traffic to HTTPS, removing HTTP access.

---

1: No redirect - Make no further changes to the webserver configuration.
2: Redirect - Make all requests redirect to secure HTTPS access. Choose this for
new sites, or if you’re confident your site works on HTTPS. You can undo this
change by editing your web server’s configuration.

I think I solved it.

Hi @siramthar

happy to read that it had worked.

I see, there are three checks of your domain ( https://check-your-website.server-daten.de/?q=mail.stage-gate.la ):

You have removed the redirect http -> https.

@siramthar

I removed the redirect from apache at /etc/apache2/sites-available/mail.stage-gate.la.conf :

RewriteEngine on
RewriteCond %{SERVER_NAME} =mail.stage-gate.la
RewriteRule ^ https://%{SERVER_NAME}%{REQUEST_URI} [END,NE,R=permanent]

But your first and second check doesn't show such a redirect. So this redirect rule or the complete vHost isn't used.

@siramthar

Select the appropriate number [1-2] then [enter] (press ‘c’ to cancel): 2
Redirecting vhost in /etc/apache2/sites-enabled/mail.stage-gate.la.conf to ssl vhost in /e
tc/apache2/sites-available/mail.stage-gate.la-le-ssl.conf

Rechecked your domain now - there is no redirect.

Looks like you have different vHosts with the same port and the same ServerName / ServerAlias.

Every combination von port and ServerName should be unique.

What says

apachectl -S
