I managed to install the site but I don’t know why the redirection from `https://www.mydoimain.com/` doesn’t work.
the rest of the addresses work, that is:
`https://mydoimain.com/` ===\> `https://mydoimain.com/ `
`http://mydoimain.com/` ===\> `https://mydoimain.com/`
`http://www.mydoimain.com/` ===\> `https://mydoimain.com/` (also work )
the problem is
http **s://www**.mydoimain.com/ - security error
What’s wrong?

Security error usually means that the SSL certificate is not valid for given domain. Have you installed a SSL certificate?

You don’t have a https cert for the www. You can search here for how to create a very cert for multiple domains, but you’ll need to modify those and it’s a bit tricky.
The easier solution I to use www instead of using the bare domain and have [forcewww.com](http://forcewww.com) redirect to the www for you.

but I’m gonna be right there. If I installed lets encrypt then why shouldn’t I have a certificate for www?
Why do I need to use external solutions?

If you want to be right then you can try [Set up Let’s Encrypt with multiple domains / redirects](https://meta.discourse.org/t/setting-up-let-s-encrypt-with-multiple-domains/56685).

Do I lose something in positioning(seo) without having this cerficate?
Can an external premium ssl certificate (from namecherp etc) help or only complicate the matter?
