→ https://example.com throws a certifcate error and is not redirected to the correct https://www.example.com (the certificate was issued for http://www.example.com and not for http://example.com)

@Elmi

What is the best approach to make https://example.com redirect to https://www.example.com and how can I achieve my goal?

If you create a cert for both the apex and the www version, you’ll have both covered. :smiley As you stated, the cert does not include your apex domain… thus the error.

Your redirects should be:

• http://example.com → https://example.com
• http://www.example.com → https://www.example.com.
• Then redirect https://example.com → https://www.example.com (your stated preferred domain).

Then no matter whether someone types in the apex domain or the www version, they’ll land on your https://www.example.com without any errors. Best practice is to include both the apex and the www on your cert. Just make sure your amended/new cert is the one being served by your server, and not the old one.
