https://www.domain.de not secure

I installed apache and using letsencrypt but I have one problem.

these are working fine:

domain.de -> https://domain.de
www.domain.de -> https://domain.de
http://domain.de -> https://domain.de
http://www.domain.de -> https://domain.de
https://domain.de -> https://domain.de

but this is not secure:
https://www.domain.de

could anyone help me?

I had a similar problem and resolved it by rewriting all www.domain.com to domain.com

do you mean a rewrite rule in the apache traccar.conf?

I have mine in .htaccess but it can also be in the conf file for each domain. But as I only have one domain it was easier to use htaccess in the domain root folder
