@hraban I'm sorry to mention this, but could you help me out a little? In case you are wondering, I have limited knowledge of CommonLisp and English, so it would be helpful if you could take that into account when you talk to me.

I couldn't reproduce this bug. However sometimes a bug can be hidden on Mac while it shows up on NixOS. This is because Mac has more global libraries available, especially for stuff like crypto.

However I did run into a different problem which I solved like this:

(source: https://stackoverflow.com/questions/54203075/hunchentoot-is-unknown-handler )

Now I can run your app:

$ nix run 
Hunchentoot server is started.
Listening on 127.0.0.1:8080.
$

It immediately exits because clack doesn't keep the app alive, so if nothing else keeps the app alive it quits. But that's not a problem with Nix, that's just how Clack works.

I can try on a NixOS virtual machine later but for now I don't see anything immediately wrong with this app.
