Not Able to consume web api (hosted in https) from mvc

Jun 12 2019 6:15 AM
I have created self sigend certificate in IIS.
 
Changed Edit binding of my web api and mvc appication with https and selected the newly created certificate.
 
In mmc first exprorted the certificate and then inported it with in personal folder.
 
I have modified my code and still I am getting the same error.
 
"The underlying connection was closed: Could not establish trust relationship for the SSL/TLS secure channel."
 
My Code:
 
    // POST: Login/Create 
    [HttpPost] 
    public async System.Threading.Tasks.Task<ActionResult> Create(Users objusers) 
    { 
        try 
        { 
            // TODO: Add insert logic here       
     
            string actionURI = "https://localhost:1100/";             
     
            Uri address = new Uri(actionURI); 
     
            HttpRequestMessage request = new HttpRequestMessage 
            (HttpMethod.Get, address); // HttpMethod.Post is also works                
     
            var cert = new X509Certificate2(@"D:\Cer\Demo.cer");                 
     
            List<string> certs = new List<string>(); 
            certs.Add(cert.Thumbprint);               
            request.Headers.Add("Thumbprint", certs); 
     
            BearerToken token = null; 
     
            using (var httpClient = new HttpClient()) 
            {  
                var tokenRequest = 
                    new List<KeyValuePair<string, string>> 
                        { 
                            new KeyValuePair<string, string>("grant_type", "password"), 
                            new KeyValuePair<string, string>("username", objusers.username), 
                            new KeyValuePair<string, string>("password", objusers.password) 
                        }; 
     
                HttpContent encodedRequest = new FormUrlEncodedContent(tokenRequest); 
     
                HttpResponseMessage response = httpClient.PostAsync(address, encodedRequest).Result; //It throws error here 
     
                if (response.IsSuccessStatusCode) 
                { 
                    token = response.Content.ReadAsAsync<BearerToken>().Result; 
     
                    Session["ApiAccessToken"] = token.access_token; 
                } 
                else 
                { 
                    Session["ApiAccessToken"] = ""; 
                } 
            } 
     
            List<BenefitElections> benefitelections = new List<BenefitElections>(); 
     
            if (Session["ApiAccessToken"].ToString() != "") 
            { 
                using (var httpClient = new HttpClient()) 
                { 
                    httpClient.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Bearer", Session["ApiAccessToken"].ToString()); 
     
                    var response = httpClient.GetAsync("https://localhost:1100/api/benefit/169548230").Result; 
     
                    if (response.IsSuccessStatusCode) 
                    { 
                        var data = await response.Content.ReadAsStringAsync(); 
                        //var myObj = data.Substring(1, data.Length - 2); 
     
                        benefitelections = JsonConvert.DeserializeObject<List<BenefitElections>>(data.ToString()); 
                    } 
                } 
     
                return View("Index", benefitelections); 
            } 
            else 
            { 
                return View("Create"); 
            } 
            //return RedirectToAction("Index", benefitelections); 
             
        } 
        catch (Exception Ex) 
        { 
            Ex.ToString(); 
            return View("Create"); 
        }             
    }
