Nginx Does Redirect, Not Proxy

I want to set up Nginx as a reverse proxy for a https service, because we have a special usecase where we need to "un-https" a connection:
==>
But what happens is that the actual https service isn't proxied. Nginx does redirect me to the actual service, so the URL in the browser changes. I want to interact with Nginx as it was the actual service, just without https.
This is what I have:
server {
listen 0.0.0.0:8080 default_server;
location /myserver {
proxy_pass
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $remote_addr;
proxy_set_header Host $host;
}
}

You have to use the proxy_redirect to handle the redirection.
Sets the text that should be changed in the “Location” and “Refresh” header fields of a
proxied server response. Suppose a proxied server returned the header field
“Location: The directive
will rewrite this string to “Location:
Example:
proxy_redirect

You can setup nginx like this if you do not want the server to do redirects:
server
{
listen 80;
server_name YOUR.OWN.DOMAIN.URL;
location / {
proxy_pass
proxy_redirect off;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
}
}
For me, this config was sufficient:
events {
}
http {
server {
location / {
resolver 8.8.8.8;
proxy_pass
}
}
}
(Note that the resolver directive has nothing to do with the problem in the OP, I just needed it to be able to proxy an external domain such as example.com)
The problem for me was just that I was missing the www. in . In the Firefox developer's console, I could see the GET request to localhost coming back with a 301, and so I thought that NGINX was issuing 301s instead of just mirroring example.com. Not so: in fact the problem was that example.com was returning 301s to redirect to , NGINX was dutifully mirroring those 301s, and then Firefox "changed the URL" (followed the redirect) straight from localhost to .
I was having a similar issue. In my case, I was able to resolve the issue by added a trailing slash to the proxy_pass URL:
before
server {
location / {
proxy_pass
}
}
after
server {
location / {
# added trailing slash
proxy_pass
}
}
