Can´t Login with Reverse Proxy about graylog2-server HOT 4 CLOSED

You made my Day. I totally overlooked this.

That's what happens if you only follow the instructions strictly, just copy&paste and don't look at the code carefully.

Thanks a lot Miranda

Can you share your reverse proxy configuration? Can you verify that the reverse proxy is also preserving cookies?

Hi,
i use the standard configuration as described in the instructions.

server
{
    listen 80 default_server;
    listen [::]:80 default_server;
    server_name graylog.ald-vt.de;
    location / {
      proxy_set_header Host $http_host;
      proxy_set_header X-Forwarded-Host $host;
      proxy_set_header X-Forwarded-Server $host;
      proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
      proxy_set_header X-Graylog-Server-URL https://$server_name/;
      proxy_pass http://127.0.0.1:9000;
    }
}

Unfortunately, I can't answer your question about the cookie because I don't know how to check it.
I have tested with different browsers in normal or incognito mode.
Only the login process does not work. If I configure the graylog server with an IP and not with localhost and thus bypass the proxy, the login works. If I now configure everything back again and use the proxy again, graylog works as long as I remain logged in.

I was able to reproduce the issue as you describe. I found the issue is with the following line:

proxy_set_header X-Graylog-Server-URL https://$server_name/;

Because nginx is not using TLS/HTTP, the web browser is rejecting setting the authentication cookie:

If you chance change

proxy_set_header X-Graylog-Server-URL https://$server_name/;

to (note https is changed to http)

proxy_set_header X-Graylog-Server-URL http://$server_name/;

The issue is resolved.
