"exceptionMessage": "Current user cannot send API requests.",

Hello all,

Just got our cloud instance up and a Second tenant  called “Demo Data Sandbox Tenant”

Trying to Auth with the rest API and I get a 500 error “

    "message": "An error has occurred.",

    "exceptionMessage": "Current user cannot send API requests.",

    "exceptionType": "PX.Data.PXException",”

I am using this in my body

{
  "name" : "*************",
  "password" : "*****************",
  "tenant": "Demo Data Sandbox Tenant",
  "branch": "" 
}

and URL is https://***********.acumatica.com/entity/auth/login

I have a local instance that I have been using for the API with no issues. Is there something I am missing for Multi Tennant?  User is an admin. Can log into the GUI no problem.

Thank you
