The error "Automatic HK downloading is disabled or failed" in MakeMKV occurs when the software cannot reach its update servers to download "Hashed Keys" (HK) required for decrypting certain Blu-ray or 4K/UHD discs. This typically happens because the disc is too new for your local database and the network request to fetch the new keys was blocked. Common Causes

Geographic Blocking: The MakeMKV key servers are often hosted in the Russian Federation, which can be flagged or blocked by certain ISPs, routers (e.g., Ubiquiti's Geo-IP blocking), or corporate firewalls.

DNS Issues: Some DNS providers, like Cloudflare (1.1.1.1), have been reported to occasionally fail to resolve the necessary hostnames for these specific downloads. makemkv automatic hk downloading is disabled or failed

Preferences Configuration: "Enable Internet access" may be unchecked in View -> Preferences -> General, which prevents the program from even attempting the download.

Interference from Security Software: Some VPNs or antivirus suites with "Web Protection" features may view the connection as a threat and terminate it. Effective Solutions Automatic SDF/HK downloading is disabled or failed messages

Understanding the "MakeMKV Automatic HK Downloading is Disabled or Failed" Error

If you’ve encountered the message "Automatic HK downloading is disabled or failed" while using MakeMKV, you aren't alone. This specific error relates to the software's ability to decrypt UHD (4K) Blu-ray discs. To understand how to fix it, you first need to understand what "HK" is and why the download fails. What is "HK"?

In the context of MakeMKV, HK stands for Hashed Keys. These are small data files required to decrypt the AACS 2.0 protection found on UHD Blu-rays. Unlike standard Blu-rays, where the software can often calculate the keys locally, UHD discs require a specific key that matches the "hash" of that particular disc version. MakeMKV is designed to automatically ping a central server to download these keys when it encounters a new disc. Why the Error Occurs

There are three primary reasons why this automated process fails:

Internet/Firewall Restrictions: The most common culprit. Your Windows Firewall, macOS security settings, or a third-party antivirus might be blocking MakeMKV from reaching the internet.

Server Downtime: The hashed key server is maintained by a small community. Occasionally, the server may go offline for maintenance or due to high traffic, causing the "failed" status.

Software Settings: The "Automatic" feature might be manually disabled in the preferences, or the "Data Directory" where keys are stored is set to a folder that MakeMKV doesn't have "write" permissions for. How to Fix It

1. Enable Internet Access in SettingsOpen MakeMKV and navigate to View -> Preferences -> General. Ensure that the box labeled "Enable internet access" is checked. If it was already checked, uncheck it, hit apply, then re-check it to "reset" the connection.

2. Configure the Data DirectoryIn that same General tab, look at the "MakeMKV data directory." This is where the downloaded _keys.db file is stored.

Ensure this path points to a valid folder (usually in your Documents or AppData).

Make sure your user account has permission to write to this folder. Check internet access & proxy

3. Manual Key IntegrationIf the automatic download continues to fail, you can bypass the system manually:

Find a reputable source for a keys.db file (the MakeMKV forums are the official hub for this).

Download the file and place it manually into the Data Directory identified in Step 2.

Restart MakeMKV; it will now read the keys locally without needing to ping the server. Conclusion

While "Automatic HK downloading is disabled" sounds like a critical failure, it is usually just a communication hiccup. By verifying your internet permissions and ensuring your data directory is correctly mapped, you can get back to archiving your UHD library in minutes.

Some security software blocks MakeMKV’s outbound connection to port 80 (HTTP) for key downloads.

This error explicitly mentions "disabled". You may have accidentally turned off the feature.

Steps:

Note: Older versions of MakeMKV label this differently. If you don’t see the option, update the software (Method 3).

Ensure you are online. Try opening a website in your browser. If you’re behind a corporate or school firewall, MakeMKV might be blocked.

HK data (often called Hashed Keys) is a set of decryption keys for BD+ protection on Blu-ray discs. BD+ is a dynamic copy protection system that changes over time. MakeMKV needs the correct HK file to decrypt and rip the disc.

Title: Troubleshooting MakeMKV: Automatic HK (Hash Key) Downloading Disabled or Failed Verify Hostkey (HK) download settings

Overview Users of MakeMKV may encounter an error message stating that "Automatic HK downloading is disabled or failed." This issue prevents the software from retrieving the necessary Hash Keys (HK) to decrypt and rip certain Blu-ray and UHD discs, particularly newer releases with advanced copy protection.

This guide outlines the common causes and provides step-by-step solutions to restore functionality.

Common Causes

Resolution Steps

Step 1: Manual Update (Most Common Fix) Often, the automatic check fails silently. Performing a manual update usually forces the download of the latest keys.

Step 2: Check Internet and Firewall Settings MakeMKV requires a stable internet connection to phone home for decryption keys.

Step 3: Verify Preferences

Step 4: Manual Key Installation (Advanced) If the automatic download continues to fail, you may need to manually download the key file (usually named MKV_vxxx.exo) from the MakeMKV forums or official website and place it in the application directory or the user data folder.
