Zoom api calls works in localhost but stops working after hosting to iis Asp.net Mvc

[Ryzen]

Hi im working on an ASP.NET MVC app that books Zoom meetings on behalf of clients and sends links to attendees via email, below is my code

var tokenHandler = new System.IdentityModel.Tokens.Jwt.JwtSecurityTokenHandler();
                    var now = DateTime.Now;
                    var apiSecret = "key";
                    byte[] symmetricKey = Encoding.ASCII.GetBytes(apiSecret);

                    var tokenDescriptor = new SecurityTokenDescriptor
                    {
                        Issuer = "issuer key",
                        Expires = now.AddDays(1),
                        SigningCredentials = new SigningCredentials(new SymmetricSecurityKey(symmetricKey),
                        SecurityAlgorithms.HmacSha256),


                    };
                    var token = tokenHandler.CreateToken(tokenDescriptor);
                    var tokenString = tokenHandler.WriteToken(token);

                    //create req

                    var client = new RestClient("https://api.zoom.us/v2/users/me/meetings");
                    var request = new RestRequest(Method.POST);
                    request.RequestFormat = DataFormat.Json;
                    request.AddJsonBody(new { topic = apply.SubjectDetail, duration = "90", start_time = apply.start_date, type = "2" });
                    request.AddHeader("authorization", String.Format("Bearer {0}", tokenString));


                    // response

                    IRestResponse restResponse = client.Execute(request);
                    HttpStatusCode statusCode = restResponse.StatusCode;
                    int numericStatusCode = (int)statusCode;
                    var jObject = JObject.Parse(restResponse.Content);
                    var HostText = (string)jObject["start_url"];
                    var JoinText = (string)jObject["join_url"];
                    var CodeText = Convert.ToString(numericStatusCode);

This works without any problem and I get a link via mail when testing on localhost

however after hosting the app to iis there is no link in the email anymore

what could be the problem? please help

Hi @Ryzen,

Are you receiving any errors? Have you tried adding some logging in your code so that you can see where the issue is happening?

Thanks,
Will
