How can i prevent that the mailcow UI is shown over http connection, so i want to disable it or having it redirected to https.
i changed /data/conf/nginx/listen_plain.active as follows:
return 301 https://$host$request_uri;
but after restarting nginx (docker-compose restart nginx-mailcow) this file (listen_plain.active) was reset to its original contents:
Many thanks in advance
