The problem was a bug in MiKTeX's installer: It did not work unless one added something to the proxy field....
This is now fixed. I therefore released a new Windows installer including the fixed MiKTeX:
http://ftp.lyx.de/LyX%202.2.2/ (will soon be at lyx.org as well)
To fix this, open the program MiKTeX update (admin) There click on the button "Connection settings" and use the option to use a proxy. As address just type in "test". (Port is 8080) and press OK.
If MiKTeX update tells you now that it cannot find the proxy, remove this setting and don't use a proxy.
