I purchased a wildcard for the following domain = *.example.com

My website URL is = https://sub.example.com

I configured redirections through apache2 VirtualHosts like this (to force "http" to "https", and "www" to "no-www") =

<VirtualHost *:80>
        ServerName sub.example.com
        ServerAlias www.sub.example.com
        ServerAdmin webmaster@example.com

        # Redirect 301 to HTTPS
        Redirect permanent / https://sub.example.com/
</VirtualHost>

<VirtualHost *:443>
        ServerName sub.example.com
        ServerAlias www.sub.example.com
        ServerAdmin webmaster@example.com

        DocumentRoot /var/www/html/example

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

        # Redirect www to no-www
        RewriteEngine On
        RewriteCond %{HTTP_HOST} ^www\.(.*)$ [NC]
        RewriteRule ^(.*)$ https://%1/$1 [R=301,L]

        # TLS
        SSLEngine               On
        SSLCertificateFile      /etc/apache2/ssl/wildcard.crt
        SSLCertificateKeyFile   /etc/apache2/ssl/wildcard.key
        SSLCertificateChainFile /etc/apache2/ssl/digicert.pem
        Header always set Strict-Transport-Security "max-age=15768000"
</VirtualHost>

Redirects are working fine for http (80) requests =

  • http://sub.example.com to https://sub.example.com ==> WORKS
  • http://www.sub.example.com to https://sub.example.com ==> WORKS

But not for https (443) requests with "www" =

  • https://www.sub.example.com to https://sub.example.com ==> ERROR

The browser returns the following error = NET::ERR_CERT_COMMON_NAME_INVALID

During my researches, I found that some people get the same problem and the provided solution is to take a wildcard to cover the "www" part.

This is my case, I have a wildcard.

Could someone tell me why I got this error ?

OK, so it seems impossible to make it work with a wildcard. I found my answer on another topic, here = https://stackoverflow.com/a/9743652/5903520
