Question: The web UI shows nothing when accessing http://192.168.1.36:8080

Answer:

If nothing shows at http://192.168.1.36:8080 (blank page, timeout, connection refused, or infinite loading), follow these troubleshooting steps in order on your Ubuntu server. Most “nothing shows” cases are caused by one of these: service not running, wrong bind address, firewall, wrong port, config issue, or browser/network problem.

1. Check if the service is actually running

sudo systemctl status qbittorrent-nox

Look for Active: active (running).
If failed / inactive / dead → see step 7.

Also check recent logs:

sudo journalctl -u qbittorrent-nox -n 50 --no-pager

Look for lines like:

WebUI: Now listening on IP: *, port: 8080 → good
WebUI: Now listening on IP: 127.0.0.1 or localhost → bad (only local access)
Any errors about binding, permissions, or crashes.

2. Test locally on the server itself

Run this directly on the Ubuntu server (via SSH or console):

curl http://localhost:8080

curl http://127.0.0.1:8080

If you get HTML code (starts with <!DOCTYPE html> or login page source) → service is running, problem is network/firewall/browser side.
If curl: (7) Failed to connect to localhost port 8080: Connection refused → service not listening or bound only to wrong interface.
If curl: (52) Empty reply from server or timeout → service running but WebUI broken/crashed.

3. Check what is actually listening on port 8080

sudo ss -tuln | grep 8080
# or
sudo netstat -tuln | grep 8080   # if netstat is installed

Expected good output: tcp LISTEN 0 128 *:8080 *:* or 0.0.0.0:8080 (listening on all interfaces).
If 127.0.0.1:8080 or nothing → WebUI is only bound to localhost.

Fix if bound to localhost only
Edit config (stop service first):

sudo systemctl stop qbittorrent-nox

Then edit (as the qbittorrent user or with sudo):

nano /var/lib/qbittorrent/.config/qBittorrent/qBittorrent.conf
# or wherever your config is (check with find / -name qBittorrent.conf)

Find or add these lines under [Preferences]:

WebUI\Address=0.0.0.0
WebUI\Port=8080
WebUI\Enabled=true

(0.0.0.0 means listen on all interfaces)

Restart:

sudo systemctl start qbittorrent-nox

Alternative: run manually with explicit bind:

sudo -u qbittorrent qbittorrent-nox --webui-port=8080 --webui-address=0.0.0.0

4. Check Ubuntu firewall (ufw)

sudo ufw status

If active, allow the port:

sudo ufw allow 8080/tcp
sudo ufw reload

5. Browser / network checks (from your other computer)

Try http://192.168.1.36:8080 in incognito/private mode (cache/extensions can break it).
Try a different browser.
Ping the server: ping 192.168.1.36 (must reply).
Test port reachability: from your PC run telnet 192.168.1.36 8080 or use online port checker.
If you get connection refused → firewall/router issue or wrong IP.
Make sure you’re on the same local network (192.168.1.x).

Stop service → delete or rename config:

sudo systemctl stop qbittorrent-nox
sudo mv /var/lib/qbittorrent/.config/qBittorrent/qBittorrent.conf /var/lib/qbittorrent/.config/qBittorrent/qBittorrent.conf.bak
sudo systemctl start qbittorrent-nox

Run once manually to see temp password in terminal:

sudo -u qbittorrent qbittorrent-nox

7. If service fails to start

Check journalctl output for errors (permissions on /var/lib/qbittorrent, missing libs, etc.).

Common fix: ensure folder ownership

sudo chown -R qbittorrent:qbittorrent /var/lib/qbittorrent

Reinstall if corrupted:
```
sudo apt reinstall qbittorrent-nox
```

Quick one-liner summary to diagnose

sudo systemctl status qbittorrent-nox && sudo ss -tuln | grep 8080 && curl -I http://localhost:8080

Run that and share the output if still stuck — it tells us almost everything.
