Redirect http subdomain to https

Question

I'm trying to redirect all requests from http://blog.example.org to https://blog.example.org.

Unfortunately I receive this error:

400 Bad Request The plain HTTP request was sent to HTTPS port

My config:

server {
    listen      80;
    server_name blog.example.org;
    return 301 https://$host$request_uri$is_args$args;
}


server {
    server_name blog.example.org;
    listen 443 ssl http2;

    root /srv/www/wordpress;
    index index.php index.html index.htm;

What is the complete nginx configuration? What does nginx `error.log` tell? — Tero Kilkanen, Sep 16 '16 at 11:53

I'm not completely sure, but I think the use of $is_args and $args is wrong here as $request_uri would contain the full request string (full URI path with arguments). Have you tried without those? Eg:

server {
    listen 80;
    server_name blog.example.org;
    return 301 https://$host$request_uri;
}

Your return statement is incorrect. You should have:

return 301 https://$server_name$request_uri;

The redirect block should be:

server {
    listen      80;
    server_name blog.example.org;
    return 301 https://blog.example.org$request_uri;
}

Try using rewrite, instead of return.

rewrite ^(.*) https://$host$1 permanent;

That's how it's done on our server. It may be a deprecated method, since it's been like this forever, but it works on nginx 1.10.0

edit: I was looking at the wrong problem. You need to add these directives to your ssl server configuration:

ssl on;
ssl_certificate /path/to/ssl/public/certificate.pem;
ssl_certificate_key /path/to/ssl/private/key.pem;
