Per the UHD FAQ:

MakeMKV says that "the volume key is unknown for this disc"?
MakeMKV produces an AACS .tgz dump file whenever you try to open a disc for which the key is unknown, and will report that the dump has been created. Email the dump file to svq@makemkv.com.

And to assist the community, also see Public KeyDB Disc Submissions.

Done

Now, it's a waiting game. For native MakeMKV functionality, what's next, etc., I recommend reading thru the 1st post of the UHD FAQ.

The alternative is explained in the 1st post of Public KeyDB Disc Submissions. It MAY get more immediate results than the 'official' process?
