Virtual Host for bjk3o77eebkax2ud.onion (donate.torproject.org) misconfigured
According to http://yz7lpwfhhzcdyc5y.onion/ the onion service version of https://donate.torproject.org/ is http://bjk3o77eebkax2ud.onion/. If you visit that URL however, you only get the default virtual host of that machine (geyeri). A virtual host for bjk3o77eebkax2ud.onion needs to be configured. The problem might also just be with this one machine, if multiple servers host that onion service via OnionBalance, I can't tell.
