What to check, and how to fix it.

What to do
A new Auth. Provider signs in at login.salesforce.com. A sandbox user signs in at test.salesforce.com. In a sandbox, open the Auth. Provider from the Named Credential chapter. Click Edit.
In Authorize Endpoint URL and Token Endpoint URL, replace login.salesforce.com with test.salesforce.com. Click Save. Then save the Named Credential again, and sign in.
