### How to fix 'unauthorized' webUI error

Add the following line to the qBittorrent.conf file:

```bash
WebUI\HostHeaderValidation=false
```

---

### Admin password not working

Adding this line under \[Preferences\], in the config file, works, for setting the default password manually to: adminadmin

```bash
WebUI\Password_PBKDF2="@ByteArray(ARQ77eY1NUZaQsuDHbIMCA==:0WMRkYTUWVT9wVvdDtHAjU9b3b7uB8NR1Gur2hmQCvCDpm39Q+PsJRJPaCU51dEiz+dTzh8qbPsL8WkFljQYFQ==)"
```

### IP address banned after too many failed attempts

Modified the qBittorrent.conf. Add a new line under:

"`[Preferences]`"

`IPFilter \ BannedIPs =`

Leave it blank after the equals "="
