SHA512 code incorrect

[reuvygroovy]

Describe the issue

I am using this secret key: "blxnmpn2m2ebd4glchipydbbsclfvh553vnjqlmuqlzyxlbjsgga"

I tried to use SHA512 and 6-digits and cannot get the authenticator to give me a correct code. This is comparing to the site https://www.authgear.com/tools/totp-authenticator/ where I was able to get a good code.
