I'm still confused, because "curl -D - https://beta.shodan.io/host/$ALIP" where $ALIP is the IP address of my Amazon Lightsail instance, gives different results depending on where I do it from.
If I do that query from home, it correctly tells me that 22, 80, and 443 are open. If I do that query from the Lightsail instance itself, I get 404. I also get 404 if I do it from work.
