I mentioned the other day that requests to walledgarden error (curl says ‘transferred a partial file’). If another instance doesn’t get a good response for these requests, then after 3 days, it’ll mark the other instance as dead, and not federate out to it. Once this happens, it’s a pain, because traffic from walledgarden doesn’t make them realise that it’s actually alive, you have to wait until it tries again and gets a successful response.
If you haven’t done so already, it might be an idea to use curl to query your site, and see what the response in nginx says.
I saw the Danish original, and it’s very bleak, but the decision-making didn’t bother me because after watching The Girl with the Dragon Tattoo I assumed that people in that part of the world have a hang-up about politeness. To the extent that a fear of being impolite overwhelms any fear for your own safety.
Maybe it made more sense than the American remake (which I’m guessing is what you’re talking about).
