Thanks, that was helpful, didnīt know that I need a privat ip..
In cpanel I have SSL/TLS Manager, and in knowledges it says nothing about needing a privat ip, it says this about configuring:
Once you've purchased an SSL certificate, you will receive an email with a link to issue the certificate. Follow these steps to configure the SSL certificate:
Once you've clicked the link in your email, it will take you to a web page to issue your SSL certificate.
On the 'Web Server Type' field, select 'cPanel/WHM' (Example)
Copy and paste the CSR which you've generated within cPanel or WHM.
Fill out the rest of the fields accordingly for the organization, company or site the SSL certificate is being issued for.
Once this is completed your SSL certificate will be issued and you will then be able to install it through the 'SSL/TLS Manager' in cPanel.
