One more thing to check: please ensure that your authenticator used by 
OAuth token endpoint ('pwd') is linked to a *password credential* that 
is actually set for the client. It is a common pitfall (as in Unity you 
can have multiple password credentials).

You can also try to use command line tool as curl to make a request to 
the token endpoint in unity. Perhaps you won't be able to easily provide 
proper token, but at least you should be able to authenticate and get 
some OAuth-level error instead of an early authN error.  This would 
confirm that correct credential is configured on Unity side.

Best,
Krzysztof
