A: No. You are bypassing a network block to allow a legal piece of ripping software (MakeMKV) to access a file that allows you to decrypt a disc you physically own for backup purposes. However, check your local laws regarding digital rights management (DRM) circumvention.
: For 4K UHD discs, advanced AACS 2.0 protection requires a unique hash key calculation to decode the movie.

If the settings are correct and the software is updated, the issue might be network-related. MakeMKV needs to "phone home" to get those keys. makemkv automatic hk downloading is disabled or failed upd
If automatic downloading remains broken (e.g., you are on an offline computer or behind a strict corporate proxy), you can manually place the key database.
Since the primary issue is often your ISP or router blocking the server's location, the most effective workaround is to "escape" your current network: Automatic HK download disabled or failed - www.makemkv.com
In some regions or on some ISP networks, the specific IP addresses for MakeMKV's key servers are throttled or blocked. If you have a VPN, try connecting to a different country and restarting MakeMKV to see if the download triggers. 5. Check the MakeMKV Forums : For 4K UHD discs, advanced AACS 2
Internet Service Providers (ISPs) worldwide frequently update their automated threat intelligence feeds. Because the fairuse.org domain distributes decryption tools, some ISPs flag it as a malicious or high-risk domain and block it at the DNS or network level. 3. Security Software and Firewall Intervention
Because the backend servers hosting the key tables often trigger regional firewall rules, using a Virtual Private Network (VPN) is the highest-success solution.
If your database lacks the specific hash key for your new disc and the download fails, MakeMKV cannot decrypt the media. You will experience long loading times followed by an error message, or a complete failure to open the disc altogether. Root Causes of the Download Failure MakeMKV needs to "phone home" to get those keys
The “Automatic HK downloading is disabled or failed” error is a rite of passage for modern MakeMKV users. It is a frustrating technical hurdle created by geopolitical internet restrictions, not a flaw in the software itself.
The error message in MakeMKV indicates that the software cannot fetch the required hashed keys (HK) needed to decrypt and rip specific Blu-ray or 4K Ultra HD (UHD) discs . This critical network issue stops MakeMKV from communicating with its central key database servers, preventing it from generating processing keys for newer retail titles.
