Describe the bug
We have upgraded rest sharp to latest stable version 112 and try to generate token through an API by passing client id and secret It is failing. However, if we try to generate similar token using older version of Rest Sharp API(106), works perfectly fine. What change, I need to do in my code snippet to suit the call

To Reproduce
var request = new RestRequest();// new RestRequest("api/attachments", Method.Post);
request.Method = Method.POST;
request.Timeout = 800000;//new TimeSpan(800000);
// request.ReadWriteTimeout = 800000;
request.AddHeader("User-Agent", "Mozilla/5.0");
request.AddHeader("Charset", "utf-8");
request.AddHeader("Content-Type", "application/json");
JObject jbody = new JObject();
jbody.Add("client_id", client_id);
jbody.Add("client_secret", client_secret);
jbody.Add("grant_type", "client_credentials");

request.AddParameter("application/json", jbody, ParameterType.RequestBody);

IRestResponse response = client.Execute(request);

Expected behavior
API should return a value which is used a token

Stack trace
No exception. Response Status code is 0

Desktop (please complete the following information):
