Got API error the remote name could not be resolved: 'accounts.zoho.com'

Hi everyone,

I get the error in the picture when I get the data transmission code working in its my local environment to the server. By the way, my code is as follows;




    public static class CrmIntegration
    {
        static string serviceUrl = "";
        static HttpClient client = new HttpClient();
        public static void InsertRecords(SendEmailCommand contactData)
        {
            Task<string> getToken = GetToken();

            if (getToken != null)
            {
                string jsonToken = getToken.Result;
                Token token = JsonConvert.DeserializeObject<Token>(jsonToken);

                HttpWebRequest request = (HttpWebRequest)WebRequest.Create("https://www.zohoapis.com/crm/v2/Leads");
                request.Method = "POST";
                request.Headers["Authorization"] = $"Zoho-oauthtoken {token.access_token}";
                JObject requestBody = new JObject();
                JArray recordArray = new JArray();
                JObject recordObject = new JObject();

                recordObject.Add("First_Name", contactData.FirstName);
                recordObject.Add("Mobile", contactData.PhoneNumber);
                recordObject.Add("Email", contactData.Email);
                recordObject.Add("Kategori", contactData.MessageType);
                recordObject.Add("Last_Name", contactData.LastName);
                recordObject.Add("Company", contactData.CompanyName);

                recordArray.Add(recordObject);
                requestBody.Add("data", recordArray);

                string dataString = requestBody.ToString();
                var data = Encoding.UTF8.GetBytes(dataString);
                int dataLength = data.Length;
                request.ContentLength = dataLength;
                using (var writer = request.GetRequestStream())
                {
                    writer.Write(data, 0, dataLength);
                }
                request.KeepAlive = true;
                HttpWebResponse response;
                try
                {

                    response = (HttpWebResponse)e.Response;
                }

                HttpWebResponse responseEntity = response;
                responseEntity.Close();
            }
        }
