Renewing expired cert

Help
1

Hi,
My cert expired Jun 6 and I had to upgrade my OS before I could update the certbot rpm. I followed instructions here about certbot >=28 and removing any reference to tls-sni-01, but still getting the same error message on renewal. Perhaps I have to do something different if it has expired?
I have been renewing the cert for years and haven’t changed anything. I don’t have a VirtualHost listening on port 80.

apachectl -t -D DUMP_VHOSTS

VirtualHost configuration:
*:443 quickening.zapto.org (/etc/httpd/conf.d/ssl.conf:56)
Perhaps the apache function is broken and I need alternative? “–webroot” didn’t work either.

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. https://crt.sh/?q=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: quickening.zapto.org

I ran this command:certbot renew

Can you add a port 80 virtual host?

It can just be something simple, like a redirect to HTTPS.

Hi @quickening

that's curious. Checking your domain there answers a http server ( https://check-your-website.server-daten.de/?q=quickening.zapto.org ):

Perhaps you have only a default port 80 vHost, not a host with

ServerName quickening.zapto.org

Check your standard config files

/etc/apache2/
|-- apache2.conf
|       `--  ports.conf
|-- mods-enabled
|       |-- *.load
|       `-- *.conf
|-- conf-enabled
|       `-- *.conf
|-- sites-enabled
|       `-- *.conf

to see, if apache2.conf has a template you can use.

I have 2 long string files under [webroot]/.well-known/acme-challenge. Both were created in 2016. I don’t have the “check-your-website-dot-server-daten-dot-de”.
I have in conf file “ServerName quickening.zapto.org:80” . I am pretty sure that means I don’t need a VirtualHost there. I believe a remote query couldn’t tell the difference anyway.

ServerName is normally something without a port. It's a name.

Change that to

ServerName quickening.zapto.org

restart your Apache and check it with

apachectl -S

OK, removing the 80 on ServerName had no effect.

I added a VirtualHost stanza for quickening.zapto.org
and now apachectl -S says:
VirtualHost configuration:
*:80 quickening.zapto.org (/etc/httpd/conf/httpd.conf:371)
*:443 quickening.zapto.org (/etc/httpd/conf.d/ssl.conf:56)
ServerRoot: “/etc/httpd”
Main DocumentRoot: “/var/www/html”
etc.
certbot renew then ran successfully and I verified the cert works.
Thanks.

Yep, now your vHost configuration looks as expected.

Happy to read that it had worked :+1:
