I moved 4 TB from ACD (not encrypted) to GDrive (adding encryption).
Now I am running a Cryptcheck to see if everything is ok.
After 10 hours I got 3 errors (but still not finished) and all of them are:
Error computing hash: failed to read nonce: bad response: 404: 404 Not Found
Of course the encrypted file are there… I downloaded them and are OK.
