Chris,

With 9.0.82, and the latest version 10, I get the same problem.
So I assume it stopped working since 9.0.74 all the way up to 9.0.82

Removing the Realm LockOutRealm did not work either.

Thanks

If you temporarily remove the LockOutRealm, does the correct password work?

If you upgrade to 9.0.82, does the correct password work?
