Application Registries Issue to generate access token

[Roshnee Dash]

Hi,

I have created a application registry  'Create an OAuth API endpoint for external clients'.

Here the webservice user has admin and snc_internal role. For this user 

when I am trying to generate the access token for this instance from postman I am receiving 401 error.
I checked with the client_id, client_secret and user password. I am sending correct value only.
But still receiving 401 issue.
Can anyone please help me with this issue? Either I am missing any step or what is the mistake on this?

@Roshnee Dash 

why your API user has admin role?

As at 1st I was getting 401 so I thought to check by proving admin it may work or not.
For the 2nd instance with the same process I am getting the access token. And for that which user I am using is don't have any access but in this mentioned instance I am facing the issue.
