MakeMKV Automatic HDR Downloading: Troubleshooting "Disabled or Failed" Errors

MakeMKV is a popular tool for ripping and converting Blu-ray discs, and one of its useful features is automatic HDR (High Dynamic Range) downloading. However, some users have reported issues with this feature, stating that it is either disabled or has failed to download HDR metadata. In this article, we'll explore the possible causes of this issue and provide step-by-step troubleshooting guides to help you resolve it.

What is MakeMKV's Automatic HDR Downloading Feature?

MakeMKV's automatic HDR downloading feature allows users to download HDR metadata for their ripped Blu-ray discs. This metadata is essential for ensuring that the ripped content is properly labeled and recognized as HDR content by media players and devices. When enabled, MakeMKV will automatically download the HDR metadata from a server, which is then stored alongside the ripped video files.

Causes of "Disabled or Failed" Errors

There are several reasons why MakeMKV's automatic HDR downloading feature may be disabled or fail to download HDR metadata:

Troubleshooting Steps

To resolve the "disabled or failed" error with MakeMKV's automatic HDR downloading feature, follow these troubleshooting steps:

| Problem | Solution | |---------|----------| | No internet | Connect online | | Blocked by firewall | Allow MakeMKV | | Server issue | Wait or download HK manually | | Outdated app | Update MakeMKV | | Always fails | Place hashedkeys.txt in .MakeMKV folder |

The error is usually a temporary network or server issue. Manually installing the HK file is the most permanent and reliable fix. Once you place the latest keys in the correct folder, MakeMKV will stop trying to download automatically and use the local copy.

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

Here are a few options for the write-up, depending on where you intend to post it (e.g., a forum, a bug report, or a technical knowledge base).

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).

If automatic download fails, you can manually install the latest keys.

Step-by-step:

Test network connectivity to the key server (open Command Prompt / Terminal):

nslookup tvdb2.makemkv.com

If this times out, your network or DNS is blocking MakeMKV.

Check MakeMKV’s log for more details:
View → Log – look for lines containing “HK”, “download”, or “failed”.

Try these solutions in order.

Common Fixes Automatic SDF/HK downloading is disabled or failed messages

How to Fix "MakeMKV Automatic HK Downloading is Disabled or Failed"

If you’ve recently tried to rip a 4K UHD disc using MakeMKV and ran into the error message "Automatic HK downloading is disabled or failed," you aren't alone. This is one of the most common hurdles for enthusiasts looking to digitize their physical media library.

The "HK" in this error stands for Hashed Keys. These keys are essential for MakeMKV to decrypt the specific protection found on UHD Blu-rays. When this process fails, your drive essentially doesn't know how to "read" the movie data. Why Is This Happening?

MakeMKV needs a specific key to decrypt the AACS 2.0/2.1 protection on 4K discs. Since new movies are released constantly, the software tries to connect to a central server to download the latest "hashed keys" automatically. The error occurs for three main reasons:

Server Downtime: The primary server hosting the keys is temporarily offline.

Firewall Restrictions: Your Windows or Mac firewall (or an antivirus) is blocking MakeMKV from accessing the internet.

Internet Settings: A configuration within the software itself is preventing the download. Step 1: Enable "Allow Unit Internet Access"

Before diving into manual fixes, ensure the software actually has permission to look for keys. Open MakeMKV. Go to View > Preferences. Navigate to the General tab. Ensure the box "Allow unit internet access" is checked. Click OK, restart the program, and try the disc again. Step 2: The Manual Fix (The "KeyDB.cfg" Method)

If the automatic download is failing because the server is down, you can provide the keys yourself. This is the most reliable long-term fix.

Download the Key File: Visit a trusted community source (like the MakeMKV forums or the "vencen.org" key database) to download the latest keydb.cfg file. Locate Your Data Directory: In MakeMKV, go to Preferences > General.

Look at the "MakeMKV data directory" path (usually C:/Users/[YourName]/.MakeMKV on Windows).

Place the File: Copy the downloaded keydb.cfg file into that folder.

Restart: Close and reopen MakeMKV. It will now look at this local file for the necessary keys before trying the internet. Step 3: Check Your Firewall and DNS

Sometimes, your ISP or a third-party firewall (like Bitdefender or Norton) flags the MakeMKV key server as suspicious.

Create an Exception: Add makemkv.exe to your firewall's "Allowed Apps" list.

Change DNS: Some users find that switching to Google DNS (8.8.8.8) or Cloudflare DNS (1.1.1.1) resolves connection issues where the software can't "find" the update server. Step 4: Ensure Your Drive is "LibreDrive" Ready

If you are trying to rip 4K UHDs and see this error, ensure your optical drive has LibreDrive-compatible firmware. Note: Older versions of MakeMKV label this differently

Standard official firmware on 4K drives often blocks the reading of encrypted sectors entirely. If your drive isn't "friendly" or flashed with decrypted firmware, no amount of key downloading will fix the issue. You can check your drive status in the right-hand information panel of MakeMKV; it should say "LibreDrive Information: Status: Enabled."

The "Automatic HK downloading failed" error is usually just a communication hiccup. By enabling internet access in settings or manually placing a KeyDB.cfg file in your data directory, you can get back to backing up your media in minutes.
