Bad domain name in SSL certificate

Hi !

I've tried certbot to generate an SSL certificate. I'm running Apache 2.4.53 on Fedora 34 server. Here's the output:
[root@fedora ~]# certbot --apache -d
Saving debug log to /var/log/letsencrypt/letsencrypt.log
Certificate not yet due for renewal

You have an existing certificate that has exactly the same domains or certificate name you requested and isn't close to expiry.
(ref: /etc/letsencrypt/renewal/

What would you like to do?

1: Attempt to reinstall this existing certificate
2: Renew & replace the certificate (may be subject to CA rate limits)

Select the appropriate number [1-2] then [enter] (press 'c' to cancel): 2

When I try to access my site (, Chrome/Firefox blocks the connexion. The site says that the domain name is Fedora in SSL certificate ! How to change it to ? Is it a bug in certbot ?

Welcome to the community @laurentdelacre

I don't see an obvious problem with the parts of the config you show.

Can you show us the result of this command?

httpd -t -D DUMP_VHOSTS

Thank you for your reply. Here's the result:
[root@fedora ~]# httpd -t -D DUMP_VHOSTS
VirtualHost configuration:
*:443 is a NameVirtualHost
default server (/etc/httpd/conf.d/ssl.conf:56)
port 443 namevhost (/etc/httpd/conf.d/ssl.conf:56)
port 443 namevhost (/etc/httpd/conf.d/vhost-le-ssl.conf:2)
*:80 (/etc/httpd/conf.d/vhost.conf:1)

You have 2 VirtualHosts with the same domain name. Can you show this one too?

#   SSL Engine Options:
#   Set various options for the SSL engine.
#   o FakeBasicAuth:
#     Translate the client X.509 into a Basic Authorisation.  This means that
#     the standard Auth/DBMAuth methods can be used for access control.  The
#     user name is the `one line' version of the client's X.509 certificate.
#     Note that no password is obtained from the user. Every entry in the user
#     file needs this password: `xxj31ZMTZzkVA'.
#   o ExportCertData:
#     This exports two additional environment variables: SSL_CLIENT_CERT and
#     SSL_SERVER_CERT. These contain the PEM-encoded certificates of the
#     server (always existing) and the client (only existing when client
#     authentication is used). This can be used to import the certificates
#     into CGI scripts.
#   o StdEnvVars:
#     This exports the standard SSL/TLS related `SSL_*' environment variables.
#     Per default this exportation is switched off for performance reasons,
#     because the extraction step is an expensive operation and is usually
#     useless for serving static content. So one usually enables the
#     exportation for CGI and SSI requests only.
#   o StrictRequire:
#     This denies access when "SSLRequireSSL" or "SSLRequire" applied even
#     under a "Satisfy any" situation, i.e. when it applies access is denied
#     and no other module can change it.
#   o OptRenegotiate:
#     This enables optimized SSL connection renegotiation handling when SSL
#     directives are used in per-directory context. 
#SSLOptions +FakeBasicAuth +ExportCertData +StrictRequire

#   SSL Protocol Adjustments:
#   The safe and default but still SSL/TLS standard compliant shutdown
#   approach is that mod_ssl sends the close notify alert but doesn't wait for
#   the close notify alert from client. When you need a different shutdown
#   approach you can use one of the following variables:
#   o ssl-unclean-shutdown:
#     This forces an unclean shutdown when the connection is closed, i.e. no
#     SSL close notify alert is sent or allowed to be received.  This violates
#     the SSL/TLS standard but is needed for some brain-dead browsers. Use
#     this when you receive I/O errors because of the standard approach where
#     mod_ssl sends the close notify alert.
#   o ssl-accurate-shutdown:
#     This forces an accurate shutdown when the connection is closed, i.e. a
#     SSL close notify alert is sent and mod_ssl waits for the close notify
#     alert of the client. This is 100% SSL/TLS standard compliant, but in
#     practice often causes hanging connections with brain-dead browsers. Use
#     this only for browsers where you know that their SSL implementation
#     works correctly. 
#   Notice: Most problems of broken clients are also related to the HTTP
#   keep-alive facility, so you usually additionally want to disable
#   keep-alive for those clients, too. Use variable "nokeepalive" for this.
#   Similarly, one has to force some clients to use HTTP/1.0 to workaround
#   their broken HTTP/1.1 implementation. Use variables "downgrade-1.0" and
#   "force-response-1.0" for this.
BrowserMatch "MSIE [2-5]" \
         nokeepalive ssl-unclean-shutdown \
         downgrade-1.0 force-response-1.0

#   Per-Server Logging:
#   The home of a custom SSL log file. Use this when you want a
#   compact non-error SSL logfile on a virtual host basis.
CustomLog logs/ssl_request_log \
          "%t %h %{SSL_PROTOCOL}x %{SSL_CIPHER}x \"%r\" %b"

Something looks like it is missing from that file. Maybe it was lost by formatting. Can you add 3 backtick characters before and after the contents of the file? Like this

Also, can you show result of this?

It looks like requests are being handled by your default VirtualHost. To avoid that, try changing the above lines in the ssl.conf file to:

<VirtualHost *:443>

# General setup for the virtual host, inherited from global configuration
#DocumentRoot "/var/www/html"


Restart Apache and show this again

httpd -t -D DUMP_VHOSTS

I've done the modification:
[root@fedora ~]# httpd -t -D DUMP_VHOSTS
VirtualHost configuration:
*:443 is a NameVirtualHost
default server (/etc/httpd/conf.d/ssl.conf:56)
port 443 namevhost (/etc/httpd/conf.d/ssl.conf:56)
port 443 namevhost (/etc/httpd/conf.d/vhost-le-ssl.conf:2)
*:80 (/etc/httpd/conf.d/vhost.conf:1)
[root@fedora ~]#

Great. It looks to be working now. Do you agree?


Yes, it works ! Thank you very much !


For future reference and others finding this thread perhaps using a search engine:

Please don't "Renew & replace the certificate" if the current certificate is just fine and the issue is with the webserver. You can check the certificates known in Certbot using certbot certificates. If the certificate you see is the correct one, there is absolutely no need to renew it, but you need to look for other causes, such as webserver configuration.
