It works all fine with one domain (https://bd78.de).
But all the other domains causes errors in all browsers like in Firefox the ssl_error_internal_error_alert for https://www.eisbaer-blog.de/ as example.
->openssl s_client -connect www.eisbaer-blog.de:443

You need to config virtual hosts for every servername. In every server section you need to config the SSL directives and you need to config the server_name, e.g.
You need to correctly set the configuration for nginx - to something like;
server {
listen 80 default_server;
listen [::]:80 default_server;
# Redirect all HTTP requests to HTTPS with a 301 Moved Permanently response.
return 301 https://$host$request_uri;
}
server {
listen 443 ssl http2;
listen [::]:443 ssl http2;
# certs sent to the client in SERVER HELLO are concatenated in ssl_certificate

ssl_certificate_key /path/to/private_key;

Actually the non www. version of the site is fine (im not concerned about that mixed content warning) the problem is when loading the site over https using www (eg https://www.ekatb.ru ) , you will see the ssl error there.
Your www-site is actually behind CloudFlare, from my point of view and indeed gives an error. But because we’re not connecting to your IP, but to CloudFlares, I’ve got no idea where the problem is.
