Error "AH02572: Failed to configure at least one certificate and key" - Contabo VPS and GoDaddy SSL certificate + domain

I've bought a Contabo VPS and domain + SSL certificate from GoDaddy. I generated the CSR from my VPS using this guide: https://uk.godaddy.com/help/apache-generate-csr-certificate-signing-request-5269

I wanted to install the SSL certificate on the VPS.

openssl req -new -newkey rsa:2048 -nodes -keyout yourdomain.key -out yourdomain.csr

This command above is the one I used for generating CSR an private key to issue the certificate. The VPS has installed Rocky Linux 9. After receiving the certificate and installing it:


<VirtualHost *:443>
        ServerName mydomain.info
        ServerAlias mydomain.info
        DocumentRoot /var/www/mydomain.info/html
        RewriteEngine on
        RewriteCond %{HTTP_USER_AGENT} "Go-http-client/1.1" [NC]
        RewriteRule .* - [F,L]

        SSLEngine on
        SSLCertificateFile /etc/ssl/private/mydomain.crt
        SSLCertificateKeyFile /etc/ssl/private/privatekey.key
        SSLCertificateChainFile /etc/ssl/private/intermediate.crt

        ErrorLog /var/www/mydomain.info/log/error.log
        CustomLog /var/www/mydomain.info/log/requests.log combined
</VirtualHost>

Restarting the httpd service I've encountered this error (ssl_error.log):

I was wondering if the domain I'm using is somehow "colliding" with this "vmi1276647.contaboserver.net" domain.

I have another Contabo VPS with SSL installed but this is the first time I'm trying to install manually an "external" SSL certificate on one of their servers. Am I missing something on apache configuration files or is it not possible to install an external SSL certificate o Contabo machines?

Thank you for your help!

Solution

  • UPDATE I commented the "SSLEngine on" row from the ssl.conf file, located under the /etc/httpd/conf.d folder and now the server started and the SSL certificate seems installed.

    I think that collided with the same directive in the VirtualHost conf.
