If that is your config, then the first server{} is used for http
connections for everything except example.org; the second server is used
for http connections for only example.org; and the third server is used
for all https connections.

https goes to server{} three; you have no redirection there.

https won't anyway, as per question 1.
http would, but only if the request actually gets to nginx. What do the
nginx logs say? Does www.example.org resolve to an address on the nginx
server, as far as this client is concerned?

See why it fails right now.
If the request does not get to nginx, change things outside nginx so
that the request does get to nginx.
If the request does get to nginx, change things inside nginx so that it
does what you want.
That probably involves no change for http, but might involve a new server
for https which is the default server, and which does the redirect that
you want. Note that the client may choose not to accept the (redirect)
response if the certificate does not match whatever name they used to
connect to the server.
Good luck with it,
