API C# authentication call failing

We have had code in production for over a year now and nothing has changed with it but when trying to do the following two lines, it throws an exception now. Here is the code:


RestClient rc = new RestClient(PROD_RINGCENTRAL_CLIENTID, PROD_RINGCENTRAL_CLIENTSECRET, true);
await rc.Authorize(PROD_RINGCENTRAL_USERNAME, RINGCENTRAL_EXTENSION, RINGCENTRAL_PASSWORD_ROC);


Then here is the following exception that occurs.
