Yes, that is exactely what is happening!

I don’t really know how to solve this problem and sadly I don’t understand it as well…
I thought this would do the redirect in the Apache Proxy?
RewriteEngine on
RewriteCond %{SERVER_NAME} =nextcloud.secureserver.de
RewriteRule ^ https://%{SERVER_NAME}%{REQUEST_URI} [END,NE,R=permanent]
Thank you very much for your help!
