Ask HN: My submission didn't show up on HN Shownew, but also isn't dead

I posted https://randomairport.onrender.com/ two days ago

It shows up in Shownew when I'm logged in, but not when logged out. So my assumption is no-one sees it.

It's not [dead] either.

My assumptions are that:

(1) The OnRender URL is auto-blocked

(2) I wrote something wrong in my content (which isn't visible now anymore so cannot check).

Got screenshots as well but too afraid to upload a URL now :D

Tried hn@ycombinator.com as well but no reply yet.

Thanks for helping out
