qBittorrent WebUI Troubleshooting

This guide addresses common issues with accessing the qBittorrent WebUI when using Deployrr, particularly when running with a VPN configuration.

Common Issues

Unauthorized Access Error

If you're encountering an "Unauthorized" error when trying to access the qBittorrent WebUI, try these solutions:

Check Host Header Validation
- Edit your qbittorrent.conf file in /home/user/docker/appdata/qbittorrent (or qbittorrent-vpn)
- Add the following line under the [Preferences] section:
```
WebUI\HostHeaderValidation=false
```
Reset Default Credentials If you can't access the WebUI with the default credentials (username: admin, password: adminadmin), you can reset them by:

a. Stop the qBittorrent container (sudo docker stop qbittorrent or dcstop qbittorrent if you use Anand's bash aliases) b. Add the following line under [Preferences] in your config file:
```
WebUI\Password_PBKDF2="@ByteArray(ARQ77eY1NUZaQsuDHbIMCA==:0WMRkYTUWVT9wVvdDtHAjU9b3b7uB8NR1Gur2hmQCvCDpm39Q+PsJRJPaCU51dEiz+dTzh8qbPsL8WkFljQYFQ==)"
```
c. Start the container (sudo docker start qbittorrent or dcstart qbittorrent if you use Anand's bash aliases) d. Log in with default credentials (username: admin, password: adminadmin) e. Set your new login details
Check Access URL
- Use your host IP address instead of localhost
- Verify the correct port in your .env file
- Access format: http://your.host.ip:port

Essential Configuration

Ensure your qbittorrent.conf has these basic settings:

[Preferences]
WebUI\Address=*
WebUI\ServerDomains=*
WebUI\HostHeaderValidation=false

[BitTorrent]
Session\DefaultSavePath=/downloads/
Session\Port=6881

[Network]
PortForwardingEnabled=false
