MakeMKV is the gold-standard tool for ripping Blu-ray and DVD discs into MKV containers while preserving original quality. One of its most critical—but least understood—features is the automatic downloading of HK (Hashed Keys). When this process fails or is disabled, users encounter the error:
“Automatic HK downloading is disabled or failed.”
This article explains what HK data is, why it matters, how the error arises, and step-by-step fixes for all major platforms.
If you are seeing the status message Automatic HK downloading is disabled or failed upd in MakeMKV, it means the software cannot connect to the online decryption key database to retrieve the necessary keys for your disc.
Here is a breakdown of why this happens and how to fix it.

Look for lines containing “Downloading HK”. makemkv automatic hk downloading is disabled or failed upd
If automatic downloading fails and you need to rip the disc immediately, you will need to find the disc key manually.
The error "Automatic HK downloading is disabled or failed" in MakeMKV occurs when the software cannot reach its server to download required Hash Keys (HK). These keys are essential for identifying and decrypting specific discs, particularly 4K/UHD titles. Why This Happens
Geoblocking: The HK files are hosted on servers often located in Russia (e.g., hkdata.fairuse.org). Many ISPs, firewalls, and routers automatically block traffic from this region due to security policies.
DNS Issues: Some DNS providers, like Cloudflare or standard ISP DNS, may fail to resolve the necessary hostnames for the key servers.
Software Blocking: Security software (like Malwarebytes) or built-in OS firewalls may flag the connection as suspicious.
Internet Access Disabled: The "Enable internet access" option might be unchecked in the MakeMKV settings under the "General" tab. Immediate Solutions
Use a VPN: Switching to a VPN and trying different exit nodes can bypass ISP-level geoblocking. When this function works, MakeMKV can decrypt discs
Change DNS: Many users reported success by switching to Google DNS ( ) to avoid resolution errors.
Mobile Hotspot: Temporarily connecting your computer to a mobile hotspot can often bypass home network restrictions to download the necessary keys.
Whitelist the Server: In your router or firewall settings, ensure that hkdata.fairuse.org and hkdata.crabdance.com are not being blocked. Manual Workaround
