if I visit my nginx site with https it is working, but with http it is downloading a file called "download" (no extension whatsoever), 57 bytes and opening it with notepad etc just shows gibberish stuff.

Here's my vhost config:

server {
    server_name www.domain.com domain.com;
    listen 80;

    return 301 https://domain.com$request_uri;

server {
    server_name www.domain.com
    listen 443 ssl;

    /* SSL Stuff */

    return 301 https://domain.com$request_uri;

server {
    server_name domain.com;
    index index.php index.html index.htm;
    listen 443 ssl;
    root /usr/share/nginx/domain.com;

    /* SSL Stuff */

    location / {
            try_files $uri $uri/ /index.php?$args;

location ~ \.php$ {
            try_files $uri =404;
            fastcgi_pass unix:/run/php/php7.0-fpm.sock;
            fastcgi_param SCRIPT_FILENAME            $document_root$fastcgi_script_name;
            include fastcgi_params;

    location ~ /\. {
            deny  all;



curl -v http:/domain.com * 
Rebuilt URL to: http://domain.com/ * 
Hostname was NOT found in DNS cache *

  • This config is OK. Check if you restated nginx, configured firewall, or something else – Alexey Ten May 28 '16 at 18:19
  • Also, check with curl -v http://domain.com – Alexey Ten May 28 '16 at 18:19
  • Thanks for you reply. I restarted several times (I tried changing parts of configs, but nothing helped), my firewall is also okay. When checking with curl I get a weird response: ▒▒ just this - doesn't show the source code like it does with https. – rzmpl May 28 '16 at 18:23
  • phpfpm should be up and running and socket should exist in /run/php/php7.0-fpm.sock. – Farhan May 28 '16 at 18:37
  • It does. PHP works - I don't think it is a PHP issue. Everything over HTTPS works, no matter if it is php or not. But if I type http:// or just the domain (in which case it should redirect to https) it just downloads a 57 byte small file called "download" - Nginx error.log doesn't show anything either. – rzmpl May 28 '16 at 18:42

I found out what caused the problem: I was using listen 80 http2; in my vhost config which apparently doesn't work. After I removed http2 from said line it is now working normally again!

  • This would have been easy for people to spot, if it had been in your question. You should not omit anything important next time you ask a question. – Michael Hampton May 29 '16 at 19:50
  • I didn't omit anything. How should I been able to know it beforehand? Wouldn't have needed to ask if I knew. But whatever, I sorted it out and that's what matters. – rzmpl May 29 '16 at 22:07

    You omitted whatever part of your configuration contained listen 80 http2; which you say was the problem. That made this impossible for anyone else to figure out. – Michael Hampton May 29 '16 at 22:29

    So glad you posted this question and followed with your solution! I just encountered this and had no idea what was causing the seemingly random file download. Removing http2 from the one non-SSL site on the server worked! – Graham Swan Jan 2 '17 at 22:26
