AADSTS70000: Authentication failed. Delegation blob grant is malformed

When trying to get the access_token using the refresh_token for my SharePoint site using WebRequest I get the following error "AADSTS70000: Authentication failed. Delegation blob grant is malformed".

I am making a POST call with the following parameters 1.grant_type 2.refresh_token 3.client_id 4.client_secret 5.resource

Wanted to check if there is something missing.
