Sounds like you don't have something configured right on your server. You'll need to do deeper investigations.

Rules where .htaccess? If I set the rules there, then the site doesn't open either. How can I check the cause of the error?
If you type https in the browser: then the site opens in https
Right, so you need to look into your Apache rules to see why this is happening.
My only suggestion would be to try changing your logging level in Apache. https://httpd.apache.org/docs/2.2/mod/core.html#loglevel
