Mon certificat Let’s Encrypt n’est pas reconnus

Bonjour,

J’ai besoin d’installer des certificats Let’s Encrypt pour mes sites web, j’ai suivi des tutoriels mais malheureusement le certificat n’est pas reconnu par les navigateurs web quand je vais sur le site. Aussi SSL Labs n’est pas capable de le trouver aussi.

Le serveur tourne sur Ubuntu 20.04 LTS et est à jour. Cerbot est aussi installer et à sa plus récente version.

J’ai déjà crée le certificat pour le site, quand le fait :

/etc/letsencrypt/list.sh

J’ai ce retour :

- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
Found the following certs:
Certificate Name: toiletselfies.ca
Domains: toiletselfies.ca
Expiry Date: 2021-04-25 01:19:33+00:00 (VALID: 89 days)
Certificate Path: /etc/letsencrypt/live/toiletselfies.ca/fullchain.pem
Private Key Path: /etc/letsencrypt/live/toiletselfies.ca/privkey.pem
- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -

Le certificat semble être là.

Mon fichier de configuration pour l’hôte virtuel ressemble à ça :

<IfModule mod_ssl.c>
	<VirtualHost _default_:443>
		ServerAdmin webmaster@toiletselfies.ca
                ServerName toiletselfies.ca

      RedirectMatch 404 "^(?!/\.well-known/acme-challenge/[\w-]{43}$)"
  </Directory>


                #ssl letsencrypt
                Include /etc/apache2/ssl_rules/ssl_toiletselfies.ca


		DocumentRoot /mnt/disk/website/toiletselfies.ca

		# Available loglevels: trace8, ..., trace1, debug, info, notice, warn,
		# error, crit, alert, emerg.
		# It is also possible to configure the loglevel for particular
		# modules, e.g.
		#LogLevel info ssl:warn

		ErrorLog ${APACHE_LOG_DIR}/error.log
		CustomLog ${APACHE_LOG_DIR}/access.log combined

		# For most configuration files from conf-available/, which are

		# following line enables the CGI configuration for this host only
		# after it has been globally disabled with "a2disconf".
		#Include conf-available/serve-cgi-bin.conf

		#   SSL Engine Switch:
		#   Enable/Disable SSL for this virtual host.
		SSLEngine on

		#   A self-signed (snakeoil) certificate can be created by installing
		#   the ssl-cert package. See
		#   /usr/share/doc/apache2/README.Debian.gz for more info.
		#   If both key and certificate are stored in the same file, only the
		#   SSLCertificateFile directive is needed.
		SSLCertificateFile	/etc/ssl/certs/ssl-cert-snakeoil.pem
		SSLCertificateKeyFile /etc/ssl/private/ssl-cert-snakeoil.key

		#   Server Certificate Chain:
		#   Point SSLCertificateChainFile at a file containing the
		#   concatenation of PEM encoded CA certificates which form the
		#   certificate chain for the server certificate. Alternatively
		#   the referenced file can be the same as SSLCertificateFile
		#   when the CA certificates are directly appended to the server
		#   certificate for convinience.
		#SSLCertificateChainFile /etc/apache2/ssl.crt/server-ca.crt

		#   Certificate Authority (CA):
		#   Set the CA certificate verification path where to find CA
		#   certificates for client authentication or alternatively one
		#   huge file containing all of them (file must be PEM encoded)
		#   Note: Inside SSLCACertificatePath you need hash symlinks
		#		 to point to the certificate files. Use the provided
		#		 Makefile to update the hash symlinks after changes.
		#SSLCACertificatePath /etc/ssl/certs/
		#SSLCACertificateFile /etc/apache2/ssl.crt/ca-bundle.crt

		#   Certificate Revocation Lists (CRL):
		#   Set the CA revocation path where to find CA CRLs for client
		#   authentication or alternatively one huge file containing all
		#   of them (file must be PEM encoded)
		#   Note: Inside SSLCARevocationPath you need hash symlinks
		#		 to point to the certificate files. Use the provided
		#		 Makefile to update the hash symlinks after changes.
		#SSLCARevocationPath /etc/apache2/ssl.crl/
		#SSLCARevocationFile /etc/apache2/ssl.crl/ca-bundle.crl

		#   Client Authentication (Type):
		#   Client certificate verification type and depth.  Types are
		#   none, optional, require and optional_no_ca.  Depth is a
		#   number which specifies how deeply to verify the certificate
		#   issuer chain before deciding the certificate is not valid.
		#SSLVerifyClient require
		#SSLVerifyDepth  10

		#   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 OptRenegotiate:
		#	 This enables optimized SSL connection renegotiation handling when SSL
		#	 directives are used in per-directory context.
		#SSLOptions +FakeBasicAuth +ExportCertData +StrictRequire
		<FilesMatch "\.(cgi|shtml|phtml|php)$">
				SSLOptions +StdEnvVars
		</FilesMatch>
		<Directory /usr/lib/cgi-bin>
				SSLOptions +StdEnvVars
		</Directory>

		#   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 send or allowed to 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 send 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 [2-6]" \
		#		nokeepalive ssl-unclean-shutdown \
		#		downgrade-1.0 force-response-1.0

Le site web charge mais montre une avis concernant le certificat. J’ai aussi un fichier de configuration pour le http pour le même site. Est-ce que c’est nécessaire d’avoir ce fichier pour le http pour être capable de déployer le certificat? Et est-ce que ces lignes peuvent être dans le fichier pour le https?

<VirtualHost *:80>
        # The ServerName directive sets the request scheme, hostname and port that
        # the server uses to identify itself. This is used when creating
        # redirection URLs. In the context of virtual hosts, the ServerName
        # specifies what hostname must appear in the request's Host: header to
        # match this virtual host. For the default virtual host (this file) this
        # value is not decisive as it is used as a last resort host regardless.
        # However, you must set it for any further virtual host explicitly.

J’ai aussi crée le fichier directives SSL :

SSLEngine on
SSLCertificateChainFile /etc/letsencrypt/live/toiletselfies.ca/fullchain.pem
SSLCertificateKeyFile /etc/letsencrypt/live/toiletselfies.ca/privkey.pem
SSLCertificateFile
/etc/letsencrypt/live/toiletselfies.ca/cert.pem

Quand je test Apache je n’obtiens aucune erreur quand je lance ces commandes :

apache2ctl configtest && apache2ctl -t

et

apache2ctl graceful

J’ai aussi recharger Apache sans erreur avec

service apache2 reload

Est-ce que il y a quelque chose erroné dans mes fichiers de configuration? Comment le faire fonctionner?

Merci pour l’aide! ;-)
