login redirect incorrect when used behind reverse proxy

[scheblein]

I have the app behind nginx on a subfolder. USE_X_SETTINGS=1 environment variable is set.

https://www.domain.tld/cdio/ -> http://127.0.0.1:5000/

Everything is working great, but when I set a password to secure the app, after login i'm redirected to https://www.domain.tld/ instead of https://www.domain.tld/cdio/

You can even see it in the address bar: https://www.domain.tld/cdio/login?redirect=/

I think the login code needs to be updated to honor the USE_X_SETTINGS=1 variable. With this set, I would expect the login page url to be: https://www.domain.tld/cdio/login?redirect=/cdio/

no problem.

version: v0.52.9
platform: linux amd64 - Ubuntu 24.04.3 LTS
nginx: nginx/1.29.4
proxy config:

        location /cdio/ {
            proxy_pass http://127.0.0.1:5000/;
            proxy_set_header Host $host;
            proxy_set_header X-Forwarded-Prefix /cdio;
            proxy_set_header X-Forwarded-Proto $scheme;

            proxy_http_version 1.1;
            proxy_set_header Connection "";
            proxy_buffering off;
        }

systemd service config snippet:

WorkingDirectory=/opt/changedetection
Environment=USE_X_SETTINGS=1
Environment=BASE_URL=https://www.domain.tld/cdio
ExecStart=/opt/changedetection/bin/changedetection.io -d /opt/changedetection/data -p 5000

Running into the same thing here.

Version: 0.54.5
Platform: Debian 12 x86_64
Apache: Apache/2.4.66 (Debian
docker-compose.yml has USE_X_SETTINGS=1 uncommented

Proxy config:

        <Location /changedetection>
                RequestHeader set X-Forwarded-Prefix "/changedetection"
                ProxyPass http://127.0.0.1:5000/
                ProxyPassReverse http://127.0.0.1:5000/
