With ruleset enabled it ends up trying https on port 80 (Lenovo themselves send a "Location: https://www.lenovo.com:80/de/"), which doesn't work of course.
However, when I remove the :80 and try https://www.lenovo.com/de/ (note the trailing slash), I get a 403.
I also tried lenovo.at, there they don't use the :80 but it still fails with the mentioned 403.
