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; 

Answer 1

Your return statement is incorrect. You should have:

return 301 https://$server_name$request_uri; 

Answer 2

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; } 

Answer 3

The redirect block should be:

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

Answer 4

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;
