The "Automatic HK downloading is disabled or failed" error occurs when MakeMKV cannot download the Hash Key (HK) table required to decrypt a specific disc . This frequently happens with 4K UHD Blu-rays when the necessary decryption key isn't already stored in your local database.   Primary Causes for Failure   Geo-IP Blocking : The HK servers (e.g., hkdata.fairuse.org ) are often hosted in the Russian Federation . Many ISPs, firewalls, and routers (like Ubiquiti or Unifi gear) automatically block traffic from this region for security reasons. DNS Issues : Your ISP's DNS may fail to resolve the specific domains used for these downloads. Software Restrictions : Antivirus or "threat protection" software may flag the download as suspicious and block it. Configuration : The "Allow contacting web server for updates" option may be unchecked in MakeMKV's settings.   Verified Workarounds   Reviewers and users on the MakeMKV Forum suggest the following fixes:   Automatic HK download disabled or failed - www.makemkv.com

Fix: "MakeMKV Automatic HK Downloading is Disabled or Failed" If you’ve recently opened MakeMKV to rip a new 4K UHD Blu-ray and were greeted by the error message "Automatic HK downloading is disabled or failed," you aren't alone. This specific error prevents the software from decrypting the disc because it can't access the necessary "Hashed Keys" (HK) required for newer titles. Without these keys, your high-def backup process grinds to a halt. Here is a straightforward guide on why this happens and how to fix it. Why is this happening? MakeMKV uses a "Hashed Key" system to decrypt the AACS protection on UHD discs. Usually, the software automatically pings a central server to download the latest keys for newly released movies. The error occurs for three main reasons: Network Restrictions: A firewall or antivirus is blocking MakeMKV from reaching the internet. Server Downtime: The primary host for the keys is temporarily offline. Security Settings: Your MakeMKV settings are configured to prevent web access. Step 1: Enable Internet Access in Settings The most common culprit is that the "Web Access" feature has been toggled off. Open MakeMKV. Go to View > Preferences (or click the wrench icon). Navigate to the General tab. Ensure the box labeled "Allow internet access" is checked. Restart the application and try loading the disc again. Step 2: Manually Update the HK Database If the automatic downloader is failing due to server issues, you can bypass it by manually providing the keys. Find a Keyfile: Visit the MakeMKV forums or trusted community repositories to find the _keys.db or the latest hashed key list. Locate your Data Directory: In MakeMKV, go to Preferences > General and look at the "MakeMKV data directory" path (usually in your Documents or AppData folder). Place the File: Download the latest keys and drop them into that specific folder. Restart: Once the file is in the directory, MakeMKV will prioritize the local file over the web download. Step 3: Check Firewall and VPNs If your settings are correct but it still fails, your system might be "stealth-blocking" the connection. VPNs: Some VPNs interfere with the specific port MakeMKV uses. Try disconnecting your VPN. Windows Firewall: Add an exception for makemkv.exe or makemkvcon.exe . ISP Blocking: In rare cases, certain ISPs block the key server domains. Switching your DNS to Google (8.8.8.8) or Cloudflare (1.1.1.1) often resolves this. Step 4: Use a Custom Key Site If the default server is down, you can point MakeMKV to a different URL. Go to Preferences > General . In the "HK data hash URL" field, you can enter a mirror link (often found on the MakeMKV "UHD FAQ" forum thread). Note: Only use URLs from the official forum to avoid malware. The "Automatic HK downloading is disabled" error is rarely a sign of a broken drive. It is almost always a connectivity or configuration issue . Start by checking your "Allow internet access" box, and if that fails, manually placing a keyfile in your data directory is a foolproof workaround.

Here’s a concise write-up explaining the error "MakeMKV automatic HK downloading is disabled or failed" , its causes, and how to resolve it.

Error Overview Error Message: Automatic HK downloading is disabled or failed Affects: MakeMKV (optical disc ripping software) Commonly seen when: Opening a Blu-ray disc that requires an HK (Host Key) update to unlock AACS encryption. makemkv automatic hk downloading is disabled or failed

What Does “HK” Mean?

HK stands for Host Key — a cryptographic key used in AACS (Advanced Access Content System) for Blu-ray decryption. As new Blu-ray titles are released, AACS keys are revoked, and new keys must be obtained. MakeMKV automatically tries to download the latest HK data from its online server to decrypt newer discs.

Why This Error Occurs

No internet connection – MakeMKV can’t reach its key server. Server-side issue – The download server is temporarily down. Firewall/AV blocking – Security software blocks MakeMKV’s outgoing request. Networking/proxy configuration – MakeMKV doesn’t respect system proxy settings. Old MakeMKV version – The software’s built-in update mechanism has changed or is disabled. Manual HK file missing or misplaced – If automatic download fails, you may need a manual private_data.tar file.

How to Fix It 1. Check Internet & Permissions

Ensure you’re online. Temporarily disable firewall/antivirus to test if they’re blocking MakeMKV. Run MakeMKV as administrator (Windows) or with proper network permissions (macOS/Linux). The "Automatic HK downloading is disabled or failed"

2. Update MakeMKV

Install the latest version from makemkv.com . Newer versions include updated built-in keys and improved download handling.
