Get transmission web interface working with web server

Question

I have my working on default port and I want to be able to use the web interface with an URL like http://my.domain/torrents.

I tried adding a location and a proxy conf to Nginx but it fail to work fully. I guess it's because of web interface redirections.

server {
    root /data/www;
    autoindex on;

    server_name localhost;

    location / {
            try_files $uri $uri/ /index.html;
    }

    location /torrents/ {
            proxy_pass_header  X-Transmission-Session-Id;
            proxy_pass         http://127.0.0.1:9091;
    }
}

This conf fail because it can't reach /transmission/rpc (404 /usr/share/transmission/web/rpc) I have tried many things and I always have something missing. transmission/rpc or transmission/upload or transmission/web or transmission/javascript/whatever...

I was able to get this working just now with the following location in my config:

      location /transmission {
              proxy_pass http://127.0.0.1:9091;
              proxy_pass_header X-Transmission-Session-Id;
              proxy_set_header Host $host;
              proxy_set_header X-Real-IP $remote_addr;
              proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
     }

When I went to /transmission/, I got a 409 error saying that I had an invalid X-Transmission-Session-Id header, but when I went to /transmission/web everything seemed to be okay.

There is a working sample in Linuxserver.io repository.

https://github.com/linuxserver/reverse-proxy-confs/blob/master/transmission.subfolder.conf.sample

If you are not using docker, the configuration may look like this.

location ^~ /transmission {
    include proxy.conf;
    proxy_pass http://127.0.0.1:9091;
    proxy_pass_header  X-Transmission-Session-Id;
}

location ^~ /transmission/rpc {
    include proxy.conf;
    proxy_pass http://127.0.0.1:9091;
}

proxy.conf is in https://github.com/linuxserver/docker-swag/blob/master/root/defaults/proxy.conf

Your config says that only urls which start with /torrents/ should be proxy_passed to http://127.0.0.1:9091. For any other url like /transmission nginx will use the first location / and hence not proxy_pass it to the backend.

If you want every request to be proxy passed to the backend, you would need this location instead of the two you have:

location / {
        proxy_pass_header  X-Transmission-Session-Id;
        proxy_pass         http://127.0.0.1:9091;
}

Thanks for your answer, I use nginx as my web server so I don't want to forward all requests to the transmission web interface. Only those coming from /torrents/. But you point out that my basic web configuration may be one part of the problem. I will continu to investigate.
