Forum: NGINX HTTPS header missing from single server

How can I make nginx set the HTTPS header in a single http/https
server?  piwik with force_ssl=1 on apache goes into a redirect loop
because it doesn't know SSL is on due to the nginx reverse proxy.
There is a piwik bug which references a similar problem and blames the
HTTPS header:

What is "the HTTPS header"?

This sounds like one or more fastcgi_param key/value pairs are not set
the way your application wants them to be set.

http://nginx.org/r/fastcgi_param is how you set them. And it
includes an example with the $https variable, which is described in
http://nginx.org/en/docs/http/ngx_http_core_module...

The usual nginx directive inheritance rules apply, so you'll want to add
your fastcgi_param line to the correct place -- possibly just after you
include the external file.

I meant to say HTTPS environment variable.

I should have mentioned that I'm using proxy_pass.  I was able to get
it working like this:

proxy_set_header X-Forwarded-Proto $scheme;
