HTTPS www to non-www on NGINX - ssl

Question

I'm having issues redirecting from www to non-www only for https/ssl. Any ideas why this might be happening? It works fine for non-secure URL's. Here's my config:
html {
# Compression
# Enable Gzip compressed.
gzip on;
# Enable compression both for HTTP/1.0 and HTTP/1.1.
gzip_http_version 1.1;
# Compression level (1-9).
# 5 is a perfect compromise between size and cpu usage, offering about
# 75% reduction for most ascii files (almost identical to level 9).
gzip_comp_level 5;
# Don't compress anything that's already small and unlikely to shrink much
# if at all (the default is 20 bytes, which is bad as that usually leads to
# larger files after gzipping).
gzip_min_length 128;
# Compress data even for clients that are connecting to us via proxies,
# identified by the "Via" header (required for CloudFront).
gzip_proxied any;
# Tell proxies to cache both the gzipped and regular version of a resource
# whenever the client's Accept-Encoding capabilities header varies;
# Avoids the issue where a non-gzip capable client (which is extremely rare
# today) would display gibberish if their proxy gave them the gzipped version.
gzip_vary on;
# Compress all output labeled with one of the following MIME-types.
gzip_types application/atom+xml application/x-javascript application/javascript application/json application/rss+xml application/vnd.ms-fontobject application/x-font-ttf application/x-web-app-manifest+json application/xhtml+xml application/xml font/opentype image/svg+xml image/x-icon text/css text/plain text/x-component;

Answer 1

OK, so I figured this out a while ago but forgot to post the answer, so here it is.
server {
listen 80;
server_name www.example.com example.com;
return 301 https://example.com$request_uri;
}
server {
listen 443 ssl;
server_name example.com;
root /home/forge/default/public;
if ($host = 'www.example.com') {
rewrite ^/(.*)$ https://example.com/$1 permanent;
}
}
How robust this is I'm not entirely sure but it works.
Essentially, you listen on port 80 for www and non-www and return a 301 redirect to the secure non-www URL. You then check in your SSL server block listening on port 443 if the host that has been requested matches the www version of the secure URL and if it does you permanently rewrite it to the secure non-www version.

Answer 2

nginx takes SSL-certificate from 'default_server' or from first described for the particular IP+port pair.
So, you should
swap SSL-enabled server blocks
or just add default_server parameter to listen directive in your second block.
