Nginx Redirect Subdomain with SSL - ssl

Question

So I've got this port 80 redirect working fine
server {
listen 80;
server_name "~^(?<subdomain>.+)\.site-box\.it$";
rewrite ^(.*)$ https://$subdomain.sitebox.co permanent;
}
But I want https to work too, because some old links are left around that have https://guy.site-box.it
But this doesn't work
server {
listen 443;
server_name "~^(?<subdomain>.+)\.site-box\.it$";
rewrite ^(.*)$ https://$subdomain.sitebox.co permanent;
}
It seems to cause nothing in the Nginx conf file to work. I just get cloudflare errors on the main site, and on the testing guy.site-box.it it just says page is not available.
Any idea how to get the SSL subdomain to work?

Answer 1

First of all you need 2 certificates: for subdomain.site-box.it and for subdomain.sitebox.co. If you have wildcard certificate - good, can use one server block. If you have separate certificate - need to create one server for each subdomain (because certificate paths are different).
Also, you need openssl with SNI support (well, almost all modern version has) and check browser/os support. SNI - it's for https name-based hosting.
Also, better use return 301 instead of rewrite. return 301 https://$subdomain.sitebox.co much better.
And finally you server block not configured well. You forgot ssl keyword and certificate paths.
server {
listen 443 ssl;
ssl_certificate ... ;
ssl_certificate_key ... ;
}
